A variety of high powered sonic weapons (SW) exist spanning the infrasonic, ultrasonic, and audible ranges. Because they are weapons which direct sound onto a target, and sound is energy, they can be considered directed-energy weapons.

These weapons produce both psychological and physical effects. They include highly directional devices which can transmit painful audible sound into an individual’s ear at great distances and infrasonic generators which can shoot acoustic projectiles hundreds of meters causing a blunt impact upon a target.

Infrasonic generators can cause negative emotions such as fear, anxiety, or depression, as well as biological symptoms like nausea, vomiting, organ damage, burns, or death—depending on the frequency and power level. Most of these weapons function between the frequency range of about 1 Hz to 30 kHz. These frequencies occur within the following waves: Extremely Low Frequency (ELF) 1 Hz to 30 Hz, Super Low Frequency (SLF) 30 Hz to 300 Hz, Ultra Low Frequency (ULF) 300 Hz to 3 kHz, and Very Low Frequency (VLF) 3 kHz to 30 kHz.1

Within the ELF region of the spectrum, there is a type of sound called infrasound, which occurs between 3 and 20 Hz. Infrasound is usually not heard, but it can be if the power level is sufficient. Next, audible noise begins for most people from about 20 Hz up to 20 kHz, and occurs between the upper ELF into the VLF ranges. Ultrasound begins in the VLF range at about 20 kHz, just above human hearing.


Infrasonic and ultrasonic generators, also called emitters, and VLF modulators, are weaponized devices consisting of a directional antenna dish, which can send acoustic pulses to a general or a specific are. In 1972 France was using infrasonic generators which operated at 7 Hz on its civilian population.

And by 1973 the Squawk Box was used by the British Army in Northern Ireland. It was a directional weapon that could target specific individuals by producing audible sound at about 16 kHz, which turned into infrasound at 2 Hz when it coupled with the ears.

In the early 1990s Russia had developed a 10 Hz VLF modulator capable of targeting individuals over hundreds of meters, causing pain, nausea, and vomiting. It was adjustable up to lethal levels. Since at least as far back as 1997, the US DOD has had an interest in creating generators in the infrasonic and ultrasonic ranges of 7 Hz and 20-35 kHz, respectively, which can cause these effects.

Such a device could also target the brain. These changes in brain frequencies cause changes in brain chemistry, which then influence thoughts and emotions. Furthermore, transmitting directed-energy using an exact frequency and modulation will trigger a precise chemical reaction in the brain, which, in turn will produce a specific emotion in the targeted individual.

INFRASOUNDwhat is frequency

Infrasound occurs within the ELF range from a few hertz up to about 20 Hz, which is the lower limit of human hearing. Normally the power of sound rather than the frequency determines the pain and damage threshold. However, from 1 to about 250 Hz the pain/damage threshold seems to increase with frequency as well as power.

So, within this range, if the power level remains the same, but the frequency is increased, more damage can occur. Other than that, power is the critical factor which causes the damage, while the frequency determines what type of damage occurs.

Infrasound travels great distances and easily passes through most buildings and vehicles. It is normally sensed by the ears, but at high power levels it can couple with the body and be felt as vibrations.

Natural examples of this include: avalanches, earthquakes, volcanoes, and waterfalls. Whales, elephants, hippopotamuses, and rhinoceros use infrasound to communicate over great distances which includes hundreds of miles for whales. An electronic example would be a large sub-woofer. Infrasound is said to be superior to ultrasound because it retains its frequency when it couples with the human body.

From about 100 to 140 decibels infrasound causes a variety of biological symptoms depending on the frequency and power level. Basically, the higher the power level, the greater the damage. The effects include: fatigue, pressure in the ears, and visual blurring, drowsiness, imbalance, and disorientation, vibration of internal organs, severe intestinal pain, nausea, and vomiting. Higher power levels can liquefy bowels, and resonate the internal organs causing death. Infrasound can also cause feelings of pressure in the chest, choking, irregular breathing patterns, and respiratory incapacitation.

High powered, low frequency sound from about 30 Hz to about 100 Hz (just beyond infrasound) causes the following biological effects: fatigue, blurred vision, bowel spasms, pain or damage to internal organs, feelings of fullness in the chest cavity, chest wall vibration, difficulty breathing, difficulty swallowing, choking, and respiratory impairment.

Infrasound causes a variety of psychological effects depending on the frequency and power level. It can cause the following: loss of concentration, disgust, apathy, sadness, depression, fear, anxiety, and panic attacks. “These transmissions” said John Alexander in his December 1980 article, The New Mental Battlefield, “can be used to induce depression or irritability in a target population.”

According to the Acoustic Weapons Prospective Assessment article, which appeared in the volume 9, 2001 issue of Science and Global Security, infrasound can produce localized earthquakes. A large room within a building can act as a resonance chamber to upset the foundation causing a miniature earthquake.
