Gangstacking and Electronic Harassment using Acoustic Weapons and Sound Technology
(draft #7.2: 11/20/24)

I'm currently being targeted by gang stalkers and in the process learned a lot about their methods and technology. The methods are based on stress and psychological torture to break people, make them fear them, and do what they want. They lie and use deception everywhere. They use acoustic weapons and technology based on sound, which is not as futuristic as some believe.

A quick summary is they invaded the apartment building I live in. The apartment below became their headquarters and they scared away other residents. People who replaced them use their names and cars left behind. This started at the end of 2023 and everyone but me was gone by May 2024. The local gang is part of the network of gangs around the world, which I verified traveling to multiple countries in Europe and being followed everywhere. They are NOT the government as some victims believe - they use false identities to fool victims (In my case they tried aliens and a cult). They are criminals and crooks and do mail theft and other criminal acts.

Sound is used to play people on the street and in stores. They can make it appear people are talking about you, but behind them is someone else using a phone as a sound projector. The technology is similar to directed sound from ultrasound tech from the late 1980s. Based on this I believe they developed what can be described as synthetic telepathy with sounds being heard inside the head. They have developed technology to hear at a distance what someone hears and speaks, and even some thoughts - this is something scientists have been able to do in the last 10 years. This is NOT mind control nor do they have control over anyone's muscles. They also have acoustic weapons that act as sonic “zap” guns to cause pain and other health issues. Most of this tech is known for 40 years. Their technique is to use these on a person's skin, joints and muscles from neighboring apartments while they are asleep causing under-skin wounds. Then they use hand-held devices to cause body vibrations making a person feel pain outside, and to cause muscle spasms trying to fool that they have control over some muscles. There are protection methods against all of these - sound-proofing materials against sonic guns, mp3 player with white-noise to block or reveal “telepathic” voices on headphones, and polyurethane foam at the back of the head to disrupt it. I confirmed the use of sound waves from infrasound to ultrasound with multiple microphones, and identified some frequencies including 7khz which has been linked to the Havana incident. What McKinney wrote about gang stacking in the 1992 report is true except pointing to the government; their tech was not as advanced and took more space (devices in pianos), she did mention stereo equipment and potential use of infrasound.

My current situation is a standoff. They are unable to get me with devices working 24/7 trying to cause pain from neighboring apartments, with 24/7 electronic harassment, and people and cars following me everywhere. I have a Ph.D and do software development, but can not do a full range of normal activities in my current situation. There is a minor chance they could use lethal methods due to what I learned, but it is very unlikely despite many threats. It is unclear how long this will continue, I’m hoping it will end soon as it is obvious their attempt to take over the building and remain hidden has failed and I’m collecting more evidence. This document can be shared, but should be considered work in progress. I will later decide if I reveal my full name.

1. Introduction

What has been termed gang-stacking and electronic harassment is done by a network of gangs in America, Europe and other parts of the world. They use various methods of harassment without direct physical contact to disrupt the lives of their victims, manipulate them to get them to do what they want, steal property and money, and other reasons. Julianna McKinney, who did a first study of this in 1992, stated that this started in 1989-1990, the roots may go further:

https://www.scribd.com/document/274049078/Gang-Stalking-and-Microwave-Harassment-By-Julianne-McKinney-Director-of-the-Association-of-National-Security-Alumni-By-Julianne-McKinney

Victims of gang stacking typically refer to themselves as “targeted individuals” (TI). There are sites such as www.targetedamerica.com and targetedindividualseurope.wordpress.com where people come together for support and exchange accounts of their experiences. Social networks and blogs also have such accounts. The following research article summarizes some of these:

   https://www.mdpi.com/1660-4601/17/7/2506 

   (The Phenomenology of Group Stalking (‘Gang-Stalking’): A Content Analysis of Subjective Experiences)

As it states common reports include stocking (sometimes very openly, sometimes with people trying to hide their faces, cars driving to follow when one leaves, etc), targeted noise and intrusive sounds (including for sleep deprivation), electronic surveillance, electronic harassment and “voice to skull” (24/7 insults and short phrases like “get out of here” and “you’re dead”, hearing being interrogated, psychological torture), “mind control” (“inserting thoughts and ideas”, “controlling thought processes”), health issues (skin peering, diarrhea, ray shocks and irradiation, trouble breathing, etc), gossip (some real, some is “street theater”), unauthorized entry to home, theft and property damage (car damage, minor theft), electronic hacking, global phenomena (moved to different cities and it continues, travel to multiple countries).

As will be explained in this document, gangs use acoustic weapons and other non-contact sound technologies and group stocking to manipulate victims' lives and senses, which often results in their stories not being believed. The gangs want to break people and get them to do what they want, to get them to fear them, to “punish” them if hired to do so. They try to do this without direct physical contact and verifiable evidence. Their tactics include lies, "playing" and fooling people, harrassment, intimidation, and psychological torture. They can steal electronic documents and attempt to use these to blackmail people. Their main technology is based on sound (from infrasound to ultrasound) which is used for electronic harassment, to cause pain, and in other ways. Accounts of the victims can all be explained with sound technologies gangs use. They follow victims everywhere, in part because they need them to be in range of sound projectors, and to intimidate and make them feel they can reach them everywhere.

They primarily operate from apartment buildings, some become their headquarters. They use false identities to stay hidden with gang members taking identities of prior residents. This is my current situation as they tried to take over my apartment building and all other residents fled or moved in the last 9 months. Several of their people are using names and cars left behind by prior residents. It's been 9 months since I detected their activity after someone came to my apartment to access my computer. I heard from below "we have been found” later. Electronic harassment and other activities started soon after. When I told the landlord, they got her.

Sound waves are used by the gangs to cause pain and health issues, to do “street theater” and harass victims in public places, to project voices into their heads, to monitor their conversations and even some thoughts. Most of this document details their sound technologies, and what I learned about it. This is not as futuristic as some think, though they worked on some parts on their own. Many of the health symptoms are similar to what US diplomats experienced in Havana in 2016 and I have confirmed use of the same 7kHz frequency as was recorded there. These symptoms are consistent with acoustic weapons as described at:
 
https://scienceandglobalsecurity.org/archive/sgs09altmann.pdf (Altmann. Acoustic Weapons.)

II. Directed Sound and "Street Theater"

How to do directed sound using ultrasound has been known from the end of 1980s and involves using 2 or more frequencies with special modulation, the result is target hears sound in audible range (approximately Perceived Freq = Freq1 - Freq2). For more information see

   https://en.wikipedia.org/wiki/Sound_from_ultrasound 

Engineering schematics for directed sound from ultrasound device can be found at:

   https://dr.ntu.edu.sg/bitstream/10220/7114/1/SPM_Audio%20Projection_GWS_double_column.pdf

Small hobbyist devices that do this can be bought on Amazon and Ebay and several companies produce specialized speakers for business and other use. In society these can be found in museums for special artistic audio experience, and other places. While direct ultrasound is how this was developed and known, this can be done with any set of sound frequencies.

Directed sound is used by the gangs to do various plays outside (and inside stores and places people visit), it is what people have reported as “street theater” around them, which may have involved more gang people at first directly. Those who their target sees talking about them are typically not involved, it's a manipulation and a real gang member is usually projecting sound from further behind with a phone-like projector. This is used as a means of harassment and to make victims think everyone everywhere is talking about their life.

III. Synthetic Telepathy

They developed technology similar to directed ultrasound further so that sound can be heard inside a head. This is still based on sounds from outside. They may try to make it appear these are thoughts and make people think it is mind control, but it is not. Voice inside the head would normally not be loud and they created “haulers” which are phrases memorized on hidden channels and later recalled in louder voices to harass people, a lot of what was reported as their communication is likely that. Their technology also includes components to monitor what victims hear and speak, and to access internally spoken thoughts (internal monologue). These components may involve sound projected to the back of the head or the skull which is reflected back and used to read the victim’s “thoughts”. This can be considered "synthetic telepathy";

Their technology mainly uses frequencies in the audible range and short duration sound pulses. Frequencies above 6-8 khz and heard as high pitch sounds or not at all. Frequencies below 20hz are also not heard. People are tuned up to certain frequencies, which results in better hearing some noise producing machines and devices such as car motors, air conditioners, and other appliances which produce low frequency 10Hz-1kHz sounds (see Altmann page 30). That audio cortex cells can become attuned and activated with certain sounds is known (one article below even says it allows "remote control of brain circuits", what was done did not go as far):

  https://news.asu.edu/content/ultrasound-shown-exert-remote-control-brain-circuits 

  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8653683/ 

  https://www.sciencedirect.com/science/article/pii/S1935861X23018740 

Keeping cells activated to better hear certain frequencies requires continuously receiving these sounds. I believe it involves micro-pulses every few ms. Absence and presence of this can be felt as entering and exiting an energy field. Intensity of this is felt as higher or lower “levels” which likely corresponds to induced intensity of vibrations (amplitude of the sound waves), Higher vibrations result in further activation of cells and is needed for sound to be heard inside the head. At very high levels a person may hear, see, and experience the environment in a surreal way comparable to the effects of drugs. Levels are increased with directed sound beams. Certain music (soft rock, some marches) and white noise reduce levels and keep them at the minimum. They can deal with some music, but not with white noise.


White
 noise can be generated with Audacity and other software and needs to span 20Hz-20kHz. At high volume a headset or a bluetooth earphone can block ultrasound plays outside. Speakers such as Soundcore Boom held at the back of the head can quickly reduce the “levels”, but make a person very sound sensitive (this is not good long term, but more clearly reveals “hidden channels” described below). White noise I generated are at:
 
https://audio.com/white_noise/collections/white-noise-collection 

   https://www.mediafire.com/file/e5nybvlf4nh03g4/white_noise2_stg24_allbands_10min.mp3/file


White noise appears to act as an amplifier, and a person listening to white noise can hear what is sent to their head on headphones or a speaker. It appears as if white noise gave access to special audio “channels” partially revealing how the technology works. It reveals multiple "channels", one used to speak to a person, another meant to be hidden and used for memorization of phrases. These may not be channels, but different sets of frequencies. The hidden channel is used to save (memorize) "haulers" which are phrases the gang uses to communicate and harass their victims. These phrases are repeated many times on the hidden channel and then recalled by using start of the phrase words. Typical;u victims do not know about memorization and hear the phrase loudly inside the head when recalled (potentially as different voices). White noise gives access to hear and potentially modify the phrase while it is being memorized, making it a positive phrase instead. This change would not be detected and known by the gang until later if they don’t have partial access to the victim's thoughts. With white

noise a voice that actually does the talking and recalling of the phrases can be heard. This voice is quiet and appears as male or female but is actually artificial. With white noise on one ear it could be heard at a higher frequency and may involve directed (ultra)sound.

A person can also hear their words repeated after they said something, sometimes with a delay. This is likely a retransmission and delay corresponds to how far gang’s transmitter is - with 343 m/s speed of sound a delay of ¼ second means it is approximately 50 meters away. White noise at a very high volume can act as a jammer, especially if the transmitter is far away. Having several inches of polyurethane foam at the back of the head also disrupts the signal and results in hearing automated phrases such as “not working”, “where are you”, “what’s happening”. Beats felt at the back of the head are associated with initial (and sometimes subsequent) attempts to do transmission and/or reception. Based on this I believe technology may involve sounds projected at the back of the head or the skull and likely reflected and used to receive audio information back. This is somewhat similar to “voice to skull” where at certain frequencies radio wave micro-pulses with enough energy can penetrate the skill and produce sound waves in the cochlea. Regular sounds penetrating the skull is known and used for hearing aids:

   https://www.hearinglink.org/your-hearing/implants/bone-conduction-hearing-devices/

There is no need for an implant, but there may be activated cells that respond to sound waves.

They can also read thoughts internally spoken. This is known to as internal (inner) monologue:
   
https://drjaci.com/inner-monologue-vs-thoughts/
   
https://irisreading.com/is-it-normal-to-not-have-an-internal-monologue/
Most people use inner monologue when reading and thinking internally. As high as 30% do not and think visually or entirely abstractly.
With an inner monologue brain speech center is used in a similar way to speaking. As described in the 2014 NewScientist article below, specific sets of cells in the temporal lobe are activated when a person hears sounds at specific frequencies, same cells are used when a person speaks and words can be represented by a “spectrogram” map. The same cells are also activated with an inner monologue which allows to hear thoughts:

  https://www.newscientist.com/article/mg22429934-000-brain-decoder-can-eavesdrop-on-your-inner-voice/ 

Multiple labs have been working on this to create a wearable device for those who can’t speak. Technically it is called BCI (Brain Computer Interface), FMRI is typically used to read the brain:

   https://www.ucsf.edu/news/2019/04/414296/synthetic-speech-generated-brain-recordings 

   https://www.media.mit.edu/articles/watch-this-device-translate-silent-thoughts-into-speech/ 
Scientists have also reported that accessing the state of brain cells is possible with ultrasound. As the article below warns, ultrasound telepathy is possible even if a person did not consent:
 
https://www.fanaticalfuturist.com/2021/07/scientists-use-ultrasound-to-read-the-minds-of-monkeys/
   https://www.caltech.edu/about/news/reading-minds-with-ultrasound-a-less-invasive-technique-to-decode-the-brains-intentions
As
 in above, gangsreception tech involves penetrating the back of the skull with sound waves.

Gangs likely developed synthetic telepathy on their own. Accessing thoughts requires an extra step and feels like an attempt to push into your head in the back. It can be resisted and pushed back with some mental effort, and disrupted with polyurethane foam at the back and/or high volume white noise. Reading thoughts does not work 100%, most thoughts are not inner monologue, and many people don’t do it or do very little. Talking while dreaming is similar to an  inner monologue, my interpretation is they may hear some words but not full dream content.

Telepathy is used to talk to victims and try to fool them with false stories, to do psychological manipulation and harassment, and to gain knowledge about their activities and plans. Phrases such as “we want to talk” repeated over and over may be used to push people into telepathic conversation. SImilar technique involves pushing targets to talk to themselves with phrases like "we know that" (when they really don't) or "what is going on is”. They want the target to continue and may attempt to encourage it with a few words said by a near silent voice that they want repeated. If a person picks on any of these phrases, the initial phrase continues playing in the background to encourage talking further. Anything learned may be used against the victim, to agitate them and get them upset and angry. What victims are told are typically lies, which may involve the victim's own false beliefs.Telepathy does not work on everyone and the gang may not reveal that’s what they are doing and just listen to thoughts. They may also try to fool that it’s not telepathy with sophisticated mind-control stories like “hijacked” part of one’s own brain.

Full telepathy with internal monologue is an extra step that the gangs may or may not do or be able to do. Without it they may still try to monitor their target’s conversations, including with authorities. Тhey may follow and listen to their conversations for some time after main activity. Using sound detectors and/or white noise may reveal their presence. Telepathy and hearing conversations require someone behind their target, typically less than 100 meters away. Thick walls and polyurethane foam in the back can disrupt this or require gangs to be very close.

IV. Use of sound to cause pain and health issues and for appearance of muscle control

Sound waves from infrasound to ultrasound are used by gangs to zap people, to cause pain and health issues, and do what some think may be body muscle control. Sound is an energy wave that results in vibrations of molecules. When the wave travels forward some energy is observed and dissipates as heat. It has non-ionizing radiation effects on biological tissue, which is not as dangerous as x-rays or alpha or gamma radiation. With high intensity it can cause pain and destruction of tissues and ultrasound has been used in surgery for 50+ years:
   https://www.nature.com/articles/205938b0 (Ultrasound as a Diagnostic and Surgical Tool” - 03/01/1965)

That sound can be used to create non-lethal sonic "zap” guns has been known for a long time. Hand-held devices like that are not very powerful and dangerous. Some have posted schematics for these "guns" which are based on small directional ultrasonic speakers:

   https://www.altrasonic.com/6015-6z-2600w-high-power-ultrasonic-transducer_p32.html 

   https://www.instructables.com/Ultrasonic-Sound-Gun-Parametric-Speaker/ 

The gang’s hand-held devices look like cell phones and pads, but have small directional speakers and can be used for zapping. As described further below they may also use these to focus on areas with under-skin wounds (areas burned when a person is asleep), which typically feels different. Zapping is done a few meters away and effects last 5-30 minutes.

More serious pain, and what some describe as body muscle control, requires more powerful devices in close proximity to where victims live and sleep. Fundamentally these work the same as sonic guns. It is done from a neighbor apartment with devices next to a wall, or below or above. In my case it is both below and from the sides as I'm surrounded by apartments taken by the gang; I heard these devices being moved below many times, and heard one being mounted on the opposite side wall to my bed with burning and pain on my neck felt a few minutes later. The gang mostly uses pads from neighboring apartments to shoot from multiple areas, and only has 2-3 more powerful devices likely hidden in furniture such as coaches, coffee tables, etc.
The main technique involves wounding and burning of skin and under-skin tissue, muscles, and joints. It is related to ultrasound cavitation used to help people lose weight by burning extra fat.
Pain and bubbles, due to burning or healing, are felt when exposed to sound (used in medicine):

   https://www.webmd.com/beauty/what-to-know-about-ultrasonic-cavitation

   https://epublications.marquette.edu/cgi/viewcontent.cgi?article=1119&context=phys_therapy_fac 

   https://www.sciencedirect.com/science/article/pii/S1350417724000646 

Gangs do it when a person is asleep. Wounded sorrow tissue may be felt by pressing on feet in the morning. There appears to be 3 settings - flaming/burning of skin in a wider area, needle-like hits which are similar to flaming but very pin-point and penetrate deeper, and pin-point shots at a specific spot felt as constant hits and eventually pain. When body tissue is wounded, flaming (likely with low 50-250hz frequencies) causes pain that is felt more than just skin heat - that is the technique they use to cause pain outside with hand-held devices. Common places they wound and cause pain are feet, upper and lower back, and spine joints. Victims can be made to feel pain in feet or joints when walking. This is done by a nearby person or a car a few meters away. Infrasound may also be used as 10hz - 20hz are human body resonance frequencies.

They also use this technique for the appearance of body and movements control. They expose  muscles in feet, legs, and other areas to (ultra)sound when someone is asleep and then cause muscle spasms with sound outside to make a person feel like someone is in control of their body. Only minor under-skin muscles can be activated and a person would still be in control of their body and movements. However they could think someone is trying to prevent movement or attempting but failing to cause them to move. Some victims thought this is mind control or due to implants and trying to make them into a “cyborg” - believing it is exactly what gangs want.

Other health issues are also linked to exposure to sound waves. They can make a person feel disoriented, lose eye focus, nauseated and other stomach issues. These are due to the effects of low frequency sounds on vestibular receptors located near cochlea in the ear:
   https://www.globalsecurity.org/military/systems/munitions/accoustic.htm
 
https://scienceandglobalsecurity.org/archive/sgs09altmann.pdf (Altmann. Acoustic Weapons. 70 pages)
 
https://www.cdc.gov/niosh/hhe/reports/pdfs/2019-0119-3362.pdf

This was reported back in 1992 by McKinney as linked to infrasound (20-50hz audible range is more effective, see Altmann), she also mentioned "upscale pianos" seen by someone in all neighbor apartments - likely used to hide early versions of directional speakers used to cause pain and health issues, and potentially electronic harassment. Skin issues can appear if exposed to low-intensity (ultra)sound for extended periods. Devices causing these are likely in a neighbor's apartment, neighbor house in close proximity is possible too or a close by parked car through tissue burning may not work as well. US diplomats in Cuba and China had similar health issues:

https://edition.cnn.com/2018/05/23/asia/us-employee-china-sound-injury-intl/index.html 


Regular burning of skin can result in accumulation of toxins. This is what Dr. Hildgarde Staninger
likely found treating targeted individuals. Her information on implants may or may not be correct:
  https://www.amazon.com/GLOBAL-BRAIN-CHIP-MESOGENS-Machines-ebook/dp/B06WW9QFWS 
If implants were ever used in the past, they are not any longer. How muscle control is done is explained above, and voices in the head are directed sound + voice to skull using sound waves.

V. Measurements of Sound Waves

I have confirmed the use of infrasound (5-20hz), audible range (20hz-20khz) and ultrasound (up to 160kHz) using phones, infrasound and ultrasound microphones. One of the main frequencies appears to be around 7kHz. This is the same frequency that has been reported during Havana incident, it’s possible this frequency is best for certain acoustic weapons:
 
https://www.youtube.com/watch?v=rgbnZG85IRo

I have used “Ultrasound Detector” and “Decibel X Pro” apps to measure sounds with phones:
 
https://play.google.com/store/apps/details?id=com.skypaw.decibel
 
https://play.google.com/store/apps/details?id=com.microcadsystems.serge.ultrasounddetector 

Decibel X is available for both Android and iPhone, its features include spectrogram, saving audio, taking video & photos, and using external microphones. Ultrasound Detector is free and has good logging and spectrogram with waterfall, but has not been maintained and requires developer mode to install on latest Android phones. Many phones do not have microphones that accurately measure sounds above 6khz and can be off by 1kHz or more. I had better results with an ultrasound detector for localizing gang transmitters when it showed activity in 6-9kHz and 18-20kHz. When gangs communicate it shows activity at ~7khz. Analysis with audacity reveals micro-pulses, detailed analysis will require more time. When traveling in Europe I noticed more use of ~20khz frequencies (I even saw a gang person switch from ~8khz to 20khz in an airport when I said I'm doing ultrasound detection after being asked if I'm taking photos). Sounds below 20khz can be produced with cell phones, some go to 25khz. They also use more powerful hand-held devices that look like phones or tablets but may have special speakers.

I also bought Pettersson u384 (up to 192khz) and Echo Meter 2 (up to 128khz) ultrasound USB microphones that work with phones and laptops. They confirmed similar frequencies, plus show 10kHz-12kHz range and activity at 25kHz. At first I saw use of ultrasound when the gang was attempting to cause pain, wth 25-30kHz, 40-50kHz, 100-110kHz peaks on different occasions:  

This later stopped, I suspect they tried different frequencies to find what works better with sound proofing materials I used. Currently I’m seeing infrasound 12hz peak with 0-1kHz waves. Low frequency pulses are used for pain or to make it felt - about every 2-2.5 seconds (0.4-0.5hz).

I also noticed activity at 12-14khz (possibly harmonics of 6-7khz) and other frequencies. Their sound wave patterns are quite sophisticated and vary in wave frequencies, amplitude, pulse frequency. pulse duration, width of directional beams and other parameters. Analysis of captured data will take some time, and so far have been limited to spectrogram analysis.

I’m starting to look into how infrasound may be used. Preliminary data (that would need to be verified with additional microphones) show micro-pulses on 2-10hz infrasound frequencies.

The pulses are in groups, in each group there are several pulses 10ms or 30ms apart. Groups are 100 to 500ms apart. These may be related to synthetic telepathy which may involve combination of sounds at different frequencies. Producing infrasound is a problem for small devices like cell phones. Above should be taken with caution and will require further verification.

VI. Personal experiences of victims of gang-stacking due to their sound technologies

Infrasound was mentioned in 1992 by Julianna McKinney as a potential base technology, and

a likely cause for nausea and some of the other health symptoms people reported. As mentioned she reported that in early 1990s gangs hid equipment in “upright pianos” and labeled devices as “stereo equipment”. Her report did not rule radio and electromagnetic waves as  technology and people focused on that due to widespread use of radio waves. This helped gangs to stay hidden, and they may have further misled victims into believing satellites, cell towers and other radio emitters are used against them, potentially by the government.

Some do report ultrasound or infrasound as a source for electronic harassment from neighbors:
   
https://forum.audacityteam.org/t/ultrasound-recording-equipment/93633/2

https://www.reddit.com/r/neighborsfromhell/comments/13z81g6/apartment_floor_vibrations_shocks_low_frequency/ 
https://www.reddit.com/r/neighborsfromhell/comments/1c6vafx/evil_upstairs_neighbor_possibly_using_infrasound/ 

“The past two weeks I have only slept 2 hours a day because the demonic upstairs couple is using a device that makes my body tremble, heart skip, a jaws clenched. Doing some research they could be pointing a subwoofer to the floor which is my ceiling and running infrasound to create a inaudible noise that makes my body shake like a tuning fork. Seen some people suggested this as revenge on bad neighbors as a last resort. Pure evil this neighbor would go on sites like this, ignore posters similar experience like mine and use their tips to harass me more”

In the two reddit posts above people experienced low frequency vibrations from upstairs or downstairs neighbors. Their experiences included whole-body vibrations, heart palpitations, brain fog (all due to vibrating whole body with wider beams which were previously described as increasing “levels”), electric-like shocks, muscle and bone aches, itchiness, muscle and limb twitching (these are due to sonic guns with narrow beams directed at specific body parts), coughing fits, stomach pain and nausea, balance problems (due to infrasound and low

frequency sounds that affect vestibular receptors in the inner ear), and other internal organ issues (possibly due to infrasound at human resonance frequencies). Their experiences are consistent with much of my own. Electronic harassment was also experienced and in one case dealt with by using brown noise which like white noise can act as a blocker and prevents increase of the “levels” and effectiveness of some of their methods. The people thought they had evil neighbors intend to drive them out, but did not connect these to gangstalking. Some targeted individual do report infrasound as a potential source for electronic harassment:

https://www.reddit.com/r/Gangstalking/comments/10xmywa/infrasoundultrasound_being_used_to_harass/

“Hello. I have been under constant duress due to incoming disturbing sounds effecting my family and I mainly during the night trying to get rest and sleep. From what I understand, the sounds tend to vibrate inner organs especially if you’re sensitive like elders and children. Vision is effected and can cause blindness from the harm these somewhat silent tactics can cause. Passing traffic seem to generate much of it and is man made intentionally to cause harm. Can anyone speak on this subject whether knowledgeable and or being targeted in this manner?”

https://www.reddit.com/r/electronics/comments/11fht4g/infrasound_i_am_a_victim_of_v2k_they_are_driving/ 

“I am a victim of v2k they are driving me to commit homicide. I was investigating infrasonic wave communication. Could this manipulation be avoided with any electronic device? Or let's make one with all of us who know something about electronics we have to stop this torture”

The Phenomenology of Group Stalking (https://www.mdpi.com/1660-4601/17/7/2506) paper mentioned before contains quotes from victims of gangstalking. The paper separated stories into quotes that were categorized. 94% of stories have reports of being followed by people in cars and on foot sometimes using disguise, Harassment and physical interference such as cars being forced off the road, foot route blocked, or people intentionally bumping are in 66% of stories. Noise reports such as door slamming and other noise from neighbors, same sound repeated from outside, pebbles being thrown, etc. are in 44% of stories. “Mind control” was reported in 40% of stories (some are below). Electronic hacking such as cell phone hacking was reported by 38% (some are below). Physical ailments reports are in 36% of stories (some are below). Slander campaign is reported in 34% of stories and consists of lies being told to others in the community about the target. Vandalism of personal property such as cars is reported by 32%. Voice to Skull is reported by 26% (some are below). Physical attacks are reported by 22% but these largely relate to sonic guns and included in physical ailments. 80% believe this is a global conspiracy and many blame the government due to high technology used. I disagree, the reports in other categories are consistent with gang tactic and criminal mischief, and the gangs purposely mislead so victims think it is the government. Their technology is sophisticated, but again people are being fooled that it is more than it is. In the stores 32% believe police are involved because their stories are not believed (there may also be real incidents; gangs are also known for using disguise), 26% believe neighbors are involved, 20% believe some medical professional are involved, 24% believe family or friends are involved, while 26% report that family or friends started being followed and experienced gang stacked after. The quotes that relate to the use of sound technologies by the gangs are below:

1. Physical ailments. These are due to use of sonic guns on head, foot, and other body parts, and the effects of low frequency sound on vestibular receptors and other organs:

“Skin is peeling off, my scalp has been burned quite a few times. I have been poisoned, diarrhoea for seven days straight until I was able to get medicine”,

“There were many nights that I was gassed and electrocuted and I did not think I would live long enough to see the daylight hours the next morning.”,

“So much gamma rays and irradiation pumped through me and it hurts”,

“My scalp has been burned quite a few times. I have been poisoned, diarrhea for seven days straight until I was able to get medicine”, “I have undergone extreme poisoning within my home. My body literally has been shocked more times than I can count. The most occurrences happen when I try to go to sleep at night. Sleep deprivation is, I am assuming, one of their favorite punishments. My skull has been fried and replaced with who knows what. At one time, I could barely leave my house because of the ‘melting’ feeling in my head. They constantly play with my heart as if it is a bean bag and it has also been subjected to their very joyful shock treatment”

2. Surveillance, listening to phone conversations, hacking. These are result of gangs monitoring what victims hear themselves (and not their cell phones) and their internally spoken thoughts:

“My ex-husband’s and my cell phones were cloned.”,

“before I got my email to confirm, they had already changed my password. They are That Quick”

, but its just as possible they stack and do street theater

“The residence I live in was electronically bugged or I was put under audio and visual surveillance”

“The perps hack into not only my telephones but all the cell phones of my family members too in order to obtain information about my travel plans so that they can arrange people at strategic locations to demonstrate street theater in”,  (Note: they may be monitoring voice communication, it means gang-stackers are always nearby. Street theater may only require 1-2 people who would use direct sound to make it appear that others are talking about them)


3. “Voice to Skull” (v2k), “Mind Control”. They do use v2k-like technology to monitor sounds a person hears and their inner monologue (internally spoken thoughts), it involves sound waves reflected off the back of the skull. Transmissions are done using sound and victims hear them in the ear, but these sounds are not loud enough to normally be heard. They are amplified by sound waves that cause vibrations and increase “levels” making audio processing cells more activated. The repeated phrases people hear are “memorized” on special channels and recalled - this is what most think is v2k and their communication as these are more loud inside the head.

“The electronic harassment and everything else comes from your neighbors.”

“They automate the V2K. It is repetitive and constant. It is comprised entirely of insults and instructions to “Go”, “Get out”, “You better get out of here”, “Dead”, “You’re in trouble” and “Out”. Over and over and over.”

“I ‘hear’ the voices of people who interrogate me and maltreat and torture me around the clock”

v2k is speaking from a man on the business end of it for four years now the most insidious evil technology”
        “
I’ve also been brainwashed via v2k n the past, to believe, alien species, i.e., insectorpeeds, anthrapods and huge arachnids are going to eat me”

“I have been a victim of 24/7 covert electronic surveillance, psychological harassment, manipulation and mind control.”

“They insert thoughts and ideas and it took me a while to work out that these were not my thoughts, not my own ideas.”

“Mind control tactics are highly sophisticated, and they have Orders that make you see reflections of yourself”

“It is part of an overt agenda to create and test mind control. They are creating weaponry tested on us.”

“People have no idea of just how far advanced the authorities are in mind control methods and the means they have to apply it.”

4. “Cyborg” (muscle manipulation) and implants. Some think implants are used to receive voice transmission, others for muscle control. Neither is true. Sonic guns are used on muscles (typically when a person is asleep) and these are activated later to cause muscle spasm or pain.

- “They are building cyborg-techniques inside of me. I don’t know how, but they are doing it wirelessly

- “I consider myself lucky in one way, if I can say that, I was surgically mutilated more than 30 years ago and I think that since than the implants in me loosened up a little bit. I went to sauna, went to baro-chamber and did many crazy things in desperation.” (Note: sauna is where sonic gun was used on this person’s muscles, they did not realize it and likely thought muscles were heated due to sauna itself)

- “I am curious about how a person like myself might get into contact with someone who can help to remove implanted devices, evaluate for implanted devices and .. to take a proactive approach to halt this sort of thing.”

VII. Dark Psychology methods used by the gang stackers. Mass shootings.

Gangs use methods of Dark Psychology and their strategy is to break people and make them psychologically unstable and fearful of them. They put a lot of stress on people, try hard to make them fear them, and manipulate their environment and senses. Don’t let any of these get to you. With electronic harassment victim hear telepathic voice(s) in their head and are subjected to psychological manipulation using various techniques of “dark psychology”:

   https://psychcentral.com/disorders/dark-psychology#techniques

   https://www.medicalnewstoday.com/articles/gaslighting

They lie and attempt to deceive all the time, use coercion, gaslighting, backstabbing (if they gain trust), guilt-tripping, use victims' fears against them, and in the end exploit them for financial and material gain if it becomes possible. Voice(s) heard inside the head or outside can be random, mimic those of family members, or well known people - all of this is just manipulation.

Gaslighting is one of their main techniques. As explained in the above site, “Gaslighting is a form of emotional abuse that involves manipulating someone into questioning their own reality, thoughts, and feelings. The goal is to make the victim question their own instincts and sanity”. To achieve this they do “street theater” plays and manipulate what victims hear and their environment. Voice(s) in the head make victims further question their reality and sanity. If people start to believe these voice(s), they will hear lies and may start to believe the government, masons, or another “powerful” entity with advanced technology is involved. The false believes can become rather sophisticated and based on person’s own prejudice, and fears:

   https://www.reddit.com/r/Gangstalking/comments/1fe03mn/mind_hacking_scandal/ 

`Illusions and false sensory experiences are used to make a dramatic “out of the world” experience. At higher “levels” there is higher activation of neurons, sounds are very vivid and the world may seem different. This is similar to when a person is drugged, and gangs may do this for real as I know they use the word “sedation” to describe when a person is put through it. The world could appear unreal in some ways. For example traffic may appear to move slower and faster, which is due to several gang cars moving slower to keep track of a pedestrian and to slow street traffic. With very vivid sounds of engines this becomes surreal. Purposeful illusions using largely sound perception and plays are used in many ways. Hearing voices in the head during that time can make it further unreal and out of the world experience. Psychologists would think these are hallucinations, but the stories victims have are real and are part of gangs plays.

Conversations may be used to find as much as possible about victims, their lives, family, and friends and their weak points. All would be used against them with deception and lies, threats to them and those they care about, coercion and other techniques of black psychology. Victims would be put under high stress and psychological torture in an attempt to break them mentally. Gangs would attempt to make it appear everything is set against the victims in the world, and to separate them from family and friends who likely would not believe their stories. Slander could be used and lies told to other people. There could be attempts to drive a wedge between victims and their associates, friends and family using false sensory data (what victims hear which is not so) and further elicit negative feelings (though voice in the head or other means) towards those close to the victims. Some victims report bein coerced to commit suicide or homicide.

There are several goals that gangs have. One is to make sure victims are not believed by authorities, family, and friends, and that they would be seen as having mental problems (which is the current official position of psychologists regarding gang-stacking). If people go to police and find no help, they could be exploited financially and their financial resources or property used by someone and yet nobody would believe it. They try to put stress on victims to such a degree as to break them, including using pain and psychological torture, to get them to do what the gang wants. For those who do not it may become a mental and physical torture that lasts many years. Some can not take it any more and commit suicide or homicide.

There have been several mass murders linked to victims of gang stacking. In some cases it was against neighbors, in others due to desperation and to bring attention to their plight:

1. In September 2013, Aaron Alexis killed 12 and injured 3 at the Washington DC Navy Yard:

   https://www.nytimes.com/2013/09/17/us/shooting-reported-at-washington-navy-yard.html 

He was a Navy veteran working as a contractor. He was targeted for several months and filed a police report that he was under surveillance in a prior month. He suffered from insomnia and thought someone was below his bed in a hotel (most likely so, gangs prefer to be below to burn under-skin during sleep and to maintain telepathy connection). He etched “end to the torment” and “better off this way” on a shotgun. The director of PACTS (People Against Covert Torture & Surveillance International), a TI support group, exchanged emails with him as well.

2. In 2014 Myron May shot 3 at the Florida State University (FSU) before being killed by police:

   https://www.nytimes.com/2014/11/21/us/florida-state-university-shooting.html 
May, a graduate of FSU, ended a successful legal career after suspecting that he was the target of a large-scale surveillance. He moved from place to place for several years and posted on social media about his experiences as a TI. His personal papers included a document “My Experiences as a Targeted Individual” where he wrote about harassment he suffered, a ten car surveillance team, failure of police to take his report, forced eviction, co-opting of an old friend to participate in the harassment, and other issues. Shoting at FSU may have been a suicide after finding no way to stop the stocking and harassment, and to bringing attention to his case.

3. In July 2016, Gavin Eugene Long was killed by police after targeting 6 and killing 4 officers:

   https://www.cnn.com/2016/07/17/us/baton-route-police-shooting/index.html 

The attack was considered related to black nationalism and anti-police sentiment of 2016. However his facebook and blog indicate that he identified as a TI and interacted with PACTS. He thought he was stocked and considered police responsible for the harassment. He left a suicide note where he railed against corrupt police officers targeting of Black Americans.

4. In August 2022, Steven Marlow killed 4 of his neighbors in Butler Township, Ohio. He was arrested by police in Kansas a day later:

   https://www.wyso.org/local-and-statewide-news/2022-08-09/steven-marlow-butler-township-ohio 

In the video he uploaded a few hours before the shooting he talked about "mind control" and telepathy. He considered his neighbors involved and culpable in mental torture he experienced. He indicated that he wanted to "help other targeted individuals” by his action. As of 2024 the trial has not taken place. He is held in a mental clinic, where psychiatrists attempted to treat him with drugs. He says he is still hearing voices, which means gang’s projectors are somewhere nearby.

https://www.daytondailynews.com/local/judge-man-accused-of-killing-4-in-butler-twp-still-incompetent-for-trial/T3BPK4EC6ZDQVE6IPXSEP37XFI/

5. Fuaed Abdo Ahmed held bank customers hostage in St. Joseph, Louisiana in 2013 and was killed by police after shooting at them. He demanded authorities remove a listening chip from his head. He left no notes related to being targeted and it is not clear if that was the case.

VIII. Protection Materials, Methods and Techniques

Targeted individuals deal with many attempts by gangs to go after them. Minor things like garbage truck noises and sirens should just be ignored. Similar for street theater, which could involve (ultra)sound to fool that some of the people near you on the street are talking about you. Stocking should either be ignored or be documented to have good evidence if you decide to press a case, read further in this document about that. If gangs steal any property or mail, report that specific incident, this is also an attempt to get you. Don’t let any of this get you as that is exactly mentally as that is exactly what the gangs want. More serious issues involve electronic harassment and attempts to cause pain - to protect you may need sound-proofing material.


Pain is caused by sonic “zap” guns, and by a similar sound projecting device in a neighboring apartment which are activated at night to cause under-skin burn. Sonic gun hits are immediately noticeable and do not last long, but gangs would attempt to do it again in the same place. Wider beams are used to vibrate the body area with under-skin burns to make pain felt.  These are also used by cars to vibrate the entire body and make a person shiver. Sound absorbing materials, such as polyurethane foam, added under cloth can protect targeted body areas. Bullet proof vests made of hard plastics, such as
Dyneema, also protect against sonic guns.

Those who live in a house are not likely to see many health and pain issues except what gangs can do with cars, a basement of a house far enough away from the street may be safe from electronic harassment too. Most victims live in apartments, and at least one neighbor is likely involved. If side neighbors are involved, it may be possible to move the bed and/or soundproof the wall. If it's due to someone below or above significant efforts are needed to soundproof the apartment floor or sealing. Just soundproofing the bed may not be enough as the gang may try to go after feet when you stand or sit in other areas. Blocking sound at the back (sitting and sleeping area) can stop monitoring of voice communications and inner monologue thoughts.

Sound-proofing materials are plastics and other synthetics, metals, glass, and concrete. Rigid synthetics (fiberglass, mineral wool, polyurethane) are the most popular and cost-effective for sound-proofing, HDPE, acrylic, polyester plastics also absorb and reflect sound well. Synthetics are not as good at low frequencies as concrete. 4" - 6” of rigid materials are needed to prevent burning due to gangs acoustic weapons, and to reveal their use as vibrations. Higher density fiberglass or mineral wool (6# per sq ft) with 4” thickness are best. Layers of materials with different properties and hardness should be used and separated by air gaps if possible. My sound proof floor design is ⅛” vinyl (bottom) - 4” fiberglass - ¼ or ½” acrylic - 2” polyurethane - ¼” HDPE (top). Best reflectors are glass and metal, water also reflects the sound well. 2" of steel may be enough to soundproof the area. Concrete blocks can be used for air gaps, porous concrete with >20% air gaps can block infrasound better than other materials. For more see:

   https://www.acoustiblok.co.uk/soundproofing-materials/

   https://www.controlnoise.com/support-tools/about-sound-waves/sound-wave-reflection/

   https://www.signal-processing.com/table.php

   https://www.insul.co.nz/media/29391/Seminar-2.pdf


With several inches of rigid material, gangs’ sound weapons are revealed by vibrations. To get through they would shoot with narrow beams that are noticed as finger-size spot vibrations. They could do it at a specific spot when a person is asleep. 10” to 20” of different materials may be needed to reduce the effect at the spot to a minimum. Slightly wider beam is used for a heat burn in an entire area such as a foot. Another setting is used to have pain felt in a problem area.  

Mattresses made of polyurethane, including "memory foam", are inexpensive and can reduce the effectiveness of projectors below. Micro-vibrations at specific spots may still be felt even with 10”. The gangs may try to fool that the effects are greater by using a projector from a side) to make pain felt. This is not effective long-term if there is no burning of skin, outside there would likely be no pain since hand-held devices are not powerful. Gangs could use several cars to have pain felt more but it is not very effective if the sleeping area is well soundproofed.

If after sleep the pain is felt in the upper body area, the sonic guns or projectors from above or the sides are used. Cotton and polyester are the best sound absorption fabric material, heavy blankets made out of these may help. Cutting boards, made out of very hard HDPE, can be used as shields over problem spots. If it is not enough, determine the source(s), if it is a side wall, put sound proofing material there, If it is from above get a 2-level bed and put a polyurethane mattress and/or other soundproofing materials on the upper level. Full sound proofing will require adding under-sealing and sound proofing over the entire room.


Best sound absorption clothing materials are cotton-acrylic blend, cotton, polyester, velour, polyurethane, kevlar. Thick clothing made of these materials can partially protect against sonic zap guns. Polyurethane foam can help prevent pain activation if placed tightly over the body in places they try to activate pain in. It can be wrapped around feet and placed under cloth, neck and back of the head pillow can be made to protect these areas. Polyester is regularly used in shoes, an option is neurotrophic xxx-wide larger size with space to add polyurethane foam for more protection. Rubber absorbs sound well and is a good material for the shoe bottom. Most wear
 protection is offered by heavy density plastics used in bullet-proof vests, such as Dyneema which is made of Ultra High Density Polyethylene (UHDPE) fibers; the HDPE board is still better.

For coping with sounds I have used white-noise. It blocks directed sound when outside, and keeps “levels” and whole body vibrations to a minimum. Telepathic communication is heard on a headset. Hauler phrases are not heard, and you get access to a channel on which they are memorized and can change the phrases into something positive by repeating the phrase with some addition. However hearing this channel may mean it would become 24/7 electronic harassment. White noise can be loud at first but eventually a person gets used to it. Volume can be adjusted as necessary, however if volume is too low body vibration may be felt if levels increase (telepathic transmissions would still be heard on the headset). White noise can be played on headset, using bluetooth earphones or holding a speaker at the back of the head. White noise can be downloaded from:

   https://audio.com/white_noise/collections/white-noise-collection 

White and Brown noises can also be generated using Frequency Generator android app:

   https://play.google.com/store/apps/details?id=com.boedec.hoel.frequencygenerator 

Frequency generators can potentially jam gang’s transmissions. Feel free to experiment with the app at frequencies 75hz - 250hz (I had some success with 130hz) and others, with beat frequencies of 1hz and 2hz. If results are positive, post about it on a public forum.

Headphones with noise cancellation are the best since they reduce the strength of sound waves from outside. Look for headphones with close to 30 db SNR or above. Using ear-plugs (potentially with headphones) can further help to deal with electronic harassment. Note that some health issues, such as nausea and stomach pain, are also due to sounds heard in the ear. However pain at the back of the head is the result of sound beams directed at those areas. A speaker held at the back can offer some protection due to the hard plastics they are made of.

Creating a neck pillow from polyurethane foam is a better alternative to deal with that.

It is possible to “disconnect" from gang monitoring communication and thoughts. There are multiple methods. One is to build a completely sound-proof room or at least an area around the head and upper body. This may require 20” of sound-absorbing plastics or other materials such as concrete or steel. Several inches of polyurethane foam at the back makes the connection very unstable and without a car with a good transmitter or you stand with your back next to a steel or cement wall this can happen. It is also possible to disconnect by mental effort. I've done so by repeating a phrase such as "all out" and getting into a “hyper” state. A speaker at the back of the head playing white nose can further help. Once disconnected, you may feel beats coming to your head. Maintaining this in an environment where their projectors are nearby is difficult.

IX. Managing psychological pressure and stress

There are many techniques for coping with psychological pressure and stress. These include understanding that they lie to you and about you, ignoring them, laughing at their threats, and others. The gangs want to find what you fear to use against you and may make many threats, either covert or direct. Do not believe anything they say, do not let these get to you - “face your fears, let them pass through you”. Do not show that what gangs do bothers you - they want an emotional reaction, which tells them it somehow got you and they would do it more. Keep calm.

Do mental and physical exercises that can help manage stress and relieve negative emotions. Yoga and meditation are known to help with these. Physical exercises such as hiking, running, cycling, weight lifting, gymnastics also help to relieve stress. Just walking around the neighborhood works too. Do not be surprised if the gang tries to disrupt you when you do these, if it happens try to continue and do it again later. Keep doing exercises and relaxation regularly. Don’t rely on alcohol and drugs, these have negative effects on your body and would not reduce your stress, and these may be used by gangs against you. For more on stress relief see:

  https://www.webmd.com/balance/stress-management/stress-management 

As specified above, assert your feelings, opinions, or beliefs instead of becoming angry. Be assertive instead of aggressive. defensive, or passive. Manage your hate and do not react aggressively towards gang stackers, show them that you know who they are and record their activities. Keep a positive attitude, and set goals for yourself. Be realistic that these may not happen quickly and keep working on your goals no matter what happens and what gangs do.

Gangs would try to undermine your self-esteem with various types of negative comments and harassment, slander, and other methods. They could try to wrack your entire life. To get through it all you need to have self-confidence in your own abilities no matter what they or anyone says, and no matter what happens. Stop yourself if you start thinking negatively about yourself, and identify the positive things about yourself. Stand up for yourself and show the gang that you’re not afraid by photographing them or in other ways. For more help with self-confidence see:

   https://www.businessinsider.com/how-to-build-your-self-esteem-2017-3#5-remind-yourself-of-your-real-worth-5 

Note that lack of sleep can result in negative feelings and low self esteem. Gangs know that and use sleep deprivation techniques. Ignore the noises they make, use earplugs and/or noise canceling headphones at all times. Try white noise - it is known to help babies sleep better. If you can't fall asleep, take melatonin one hour before going to bed. If you awake at night, start counting. If your mind wanders away, start at 1 again. Don't pick up the phone, don’t look at the clock, don’t do anything interesting - you want to bore yourself to sleep.

Do not let the gang take over all your life. They may stock, annoy and electronically harass 24/7 so it would seem like you have nothing to look forward to. While life may become very stressful, and getting through it all and fighting them is important, do other things even if they are minor, and set goals for the future. Ask what you liked doing that made you relax and feel good, like watching tv, reading, cooking, etc. Start going back to these activities if they were disrupted. Consider keeping a journal, written or audio, and record what happened to you on a daily or weekly basis. Record what the gang has attempted to do, but focus on what you have been able to achieve despite their attempts to screw up your life. Reducing their impact on your life and doing what you want no matter if they are around or not, is the way to defeat them. See yourself in the future where they are no longer there, and it will come no matter what they do and say.

Gangs are trying to cause psychological damage to victims, so it would be appropriate to end here with advice to seek psychologist help. However psychologists’ view gangstalking as a potential mental illness and stories such as “mind control” or “telepathy” may lead to incorrect diagnosis and treatment that has no or negative effects. Each person must decide on their own if psychologist help would be helpful. Some of what is above is part of Positive Psychotherapy, see below for more information and exercises, which you can try doing on your own:

X. Collecting Photo and Video Evidence of Stacking

Gang members attempt to follow their victims everywhere. They can be very close by or keep at a distance. Generally they just need victims within sound equipment range, people following on foot do not have good equipment, while cars do and can be 100 meters away to keep a person potentially connected with synthetic telepathy. If you have polyurethane foam in the back of the head or other similar sound-proofing material they have to be much closer to be connected, access to hidden channels with white-noise would reveal connection failure in many places.

Following on foot nearby is common even if cars are used. They try to be near their targets everywhere including public transit such as airports, trains, buses, etc. They stock victims in shops, markets, cafes and may do street theater or electronic harassment with directed sound. Some of those who follow victims look like they are in a gang or in some other way not fit in the area. Almost all have cell phones in their hands, sometimes holding them to their head horizontally. In cafes, shops, and supermarkets people who seem to be talking about you would typically not be the ones “playing” you, gang members would hide further behind with their phones or sometimes a covered cart. In cases when you just hear general name calling or feel pain, look for a person in a nearby aisle or a corner doing it. The purpose of stocking is to let victims know they are being followed and make them uncomfortable everywhere, to know where they are at all times and to keep a connection using synthetic telepathy if it is active.

Gangs are bullies who are afraid of direct confrontation and being identified. While evidence of stacking may not quickly persuade authorities, it can help in the long term if there is enough, and is a useful tool against the stackers. Take their photographs and you may see them going away and even run if you go after them. Wearing smart glasses with a camera, such as ones from Oho for $50-$100, allows you to take video everywhere (make sure to randomly change wifi password or disable it, or gang may attempt to access it). The gang now often sends people in masks to follow me, and cars drive off quickly so I can’t get close to see who the driver is.

Cars can be photographed and videos taken, but to have evidence of stacking you’d need good photos of license plates and the same cars documented in different places. If you are driving, front and rear cameras can be installed in your car. The gang may purposely use very similar or same model cars, I've just found 3 of the same model cars I've seen following me parked on an adjacent street. Gang cars often do not have front license plates. On several occasions I also noticed no rear plates, use of shaded rear plate holder (when I shined the light the plate was not real) and other tricks - these may have started when they realized I’m recording all cars, and is in itself useful as evidence of gang activity even if the license plate is not recorded.

Gang cars can often be identified due to having their lights on. This includes both cars on the road and those that are parked on the side of the street. It is possible that they have sound projectors installed on the sides with a power connection to car lights. Once, I also observed blinking red light on the side that was not a turn signal. Cars that follow victims would be behind, some parked on slides, and some just standing on the street further ahead. If you approach one or several cars may drive off which is quite noticeable. They may try to hide the cars involved and use inter-block and side-streets. When they follow a pedestrian they need to be around in all directions, while for a car they would follow close behind and ahead if they can. Cars parked near your home can be easier to document, and they would most often have some near you, potentially used for sound projection. If a gang member stays in the car, they could park anywhere including private home spaces, they also would have access to many local garages.

Sound measurements can be taken by cell phones, see measurement section about that. Use of directional sound beams is difficult to prove, but there do exist Acoustic Cameras that can identify these. Acoustic cameras are made of a grid of microphones that sample with a minor time difference and use beamforming mathematics method to map the sound in an area:

   https://en.wikipedia.org/wiki/Acoustic_camera
These cameras use expensive hardware, cost $4000 to $20,000, and are used for industrial purposes. I have yet to get one, but if those reading this have access to them, it could provide evidence of gangs’ acoustic weapons for authorities. These are more likely to be useful inside.
In rare cases security and other cameras can also capture sound beams. One explanation is that a beam of sound with high amplitude (>100db) exerts high pressure and causes non-linear effects that may be captured with cameras. This is similar to recording shock waves:
 
https://www.americanscientist.org/article/high-speed-imaging-of-shock-waves-explosions-and-gunshots 

Gang’s weapons are like shock waves - high energy sound fragments that cause heat burns. Another phenomenon is a light reflection that can happen when air moves with a sound beam in a near dark room. Either could explain a security camera photo sent by a targeted individual to a reporter:

  https://thereporters.org/article/a-targeted-individual-follow-up/

Of note is that a number of targeted individuals attempted civil cases in federal and state courts against the government and other organizations they believed responsible. Some had what they thought were implants, but none could prove it. The courts rarely proceed without sufficient evidence based purely on one person testimony, all cases that I know of have been dismissed. Further the government is not who is behind gang stacking, gangs fool people to deflect blame and make it less likely that law enforcement and the government would interfere. It is best to collect as much evidence as possible first and then to report to law enforcement. A collective tactic to defeat the gangs is to collect from many sources and use political pressure to persuade the government to investigate the gang-stacking. Evidence collected by each individual would then prove useful in uncovering identities of people involved and bringing them to justice.

XI. Public Transportation and Worldwide Stacking

Gangs in a gang-stacking network are spread around the world. I have traveled to several cities in the United States and Europe being followed everywhere. Countries I have been to besides the USA are Portugal, Spain, England, Poland, and Turkey. Teams that follow switch after you cross the country border. In the same country, the same team may follow to other cities. In small cities and islands a team sent to follow is under 10 people and the entire team can be identified and photographed in a few days. In larger cities, those following are assisted by a local gang.

If the gang knows what tickets a victim bought (typically by monitoring thoughts) they would have a number of people on the same flight. If you board near the last moment you may notice some of them waiting for you to board and the gang tries to have at least one person board after you. If they don't know a specific flight they may reserve tickets to nearby departing flights and split the team between gates. If you are not near the gate you are going to, they would board at least one person to every flight in case you come in at the last moment. Gangs often try to reserve the last row and have their people with phones project sound across the plane. On flights TIs should choose window seats preferably near the engine with back facing the window.

The airport terminals are covered by sending people with phones, and using portable projectors hidden in luggage carts. Departing and arriving areas may be covered by cars that circulate and stop for a few minutes. A small number of airport employees could be working with the gang, these may include cleaning staff, catering/food, sometimes a single flight attendant on a flight, and in rare cases contract security guards (not TSA from what I could tell).

Using city public transport or renting a car is best. Some taxi and uber/lyft drivers are affiliated with a gang and would try to be the first ones to arrive. In such cars special beats (~1hz pulses) may be used in an attempt to get the “levels” high quickly.

A small number of public employees, hospital staff, and even police officers affiliated with the gang exist. But it is never the entire police force or staff in any place, it would only be a few people and they would try to get them to come even if it’s not their main job. For hospitals randomly going to any is safe. Your regular doctors are unlikely to be affiliated with a gang, and it would be better not to discuss details of your experiences with them. But If you do need help with pain or other health issues, note that you believe these are due to acoustic weapons.

XII. Conclusion

Gang-stacking gangs exist all over the world and use acoustic weapons and technologies based on sound to harass, intimidate, and cause pain to people while avoiding direct physical contact and prosecution. They hide who they are and make it appear their technology is very advanced resulting in victims’ stories not being believed. However the technologies they rely on are either known or developed from known technologies. They can not do remote body or mind control as some have reported, but have developed synthetic telepathy using sound waves and directed sound, and use these to stock, electronically harass and monitor their victims. They use sonic guns and other acoustic weapons to cause pain and health issues, and electronic harassment together with gas-lighting and other methods of dark psychology to ruin people's lives and well being. They attempt to stress victims psychologically in the hope of breaking them and making them do what gangs want and then exploiting them financially or in some other way. The world wide network allows gangs to follow their victims nearly everywhere and to make it appear there is no way to escape. This is part of their strategy to break people and make them fear them.

Gangs heavily use lies and manipulations and what they say should not be believed. They are not the government experimenting on people as some believe due to how gangs misrepresent themselves and shift blame. By hiding the truth of what they do and how, the gang-stacking network has been able to stay hidden from authorities and knowledge of most people. With no outside threat they have significantly increased in size in the last 30 years. Many had significant disruptions to their lives and finances, and have had to deal with long-term psychological issues, h issues, pain, harassment and threats continuing for months and even years. How many people in the world have been affected is unclear, but it could be as many as 1% in Western countries. The societal damage due to their activities is significant and there have been a number of mass murders committed by victims, often to bring attention to their plight.

Gangs' acoustic weapons have limits and can all be defeated by using sound proofing materials and other methods described in this document. The gangs are bullies and fear being discovered and those who can stand up to them and know why they are. Collecting evidence of stocking, their use of sound, and other activities, and bringing it to public and government attention is a path to defeat them. Their activities are very harmful to society and must be stopped and authorities persuaded that what they do is real and they are a significant threat in the world.
