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.
Within the ELF region of the spectrum, there is a type of sound calledinfrasound, 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.
Another sound factor is power, usually described using a unit of measurement called a decibel. Decibels are used to measure the power of audible and inaudible sound, both of which produce effects. Any sound begins to become physically painful at about 120 decibels, although at lower levels it can cause discomfort. At about 130 decibels it becomes unbearable. In this chapter, words such as intensity, level, power, pressure, and decibel, are all used to describe sound power.
All of the chemical reactions in the cells of living organisms are caused by the electromagnetic oscillations, pulsations, and vibrations, which are collectively referred to as vibrational frequencies. All physical matter is vibrating at its own vibrational frequency.
Resonance occurs when a connection is made between a source and a target which are vibrating at the same frequency. When this happens, the materials become joined and are said to be resonating. Once resonance has been achieved, an energy exchange takes place on the surface of the membrane of each cell. If the source of energy is more powerful, it directly impacts the targeted material resulting in a biological reaction.
Both infrasound and ultrasound are capable of producing resonance. This link can be established in the audible or inaudible sound ranges. A natural example of this harmonious synchronicity is frogs that sing in chorus. Mechanical examples include the pendulums of multiple clocks on the same wall which all swing in the same manner, or the string of a piano which vibrates after the same note is played on a nearby guitar.
Some organic and inorganic objects can function as resonance chambers. These objects are usually enclosures with a small opening. For instance, a glass or bottle will act as one. On a larger scale, the chest/abdominal area of the human body functions as a resonance chamber. Even an entire room with an open door or window can be used as a resonance chamber. Sound can be used to shatter or explode objects after resonance has been achieved.
Resonance can be induced electromagnetically by an infrasonic pulse generator, which can establish a link, for instance, to a person’s inner organs by resonating it in their chest area. Once this connection occurs, the power level of the generator can be increased, which would automatically transfer the energy to the person. If the power level is moderate, the person may experience pain in the chest area, or their organs may vibrate. Increasing the power level will destroy their organs.
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.2
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, visual blurring, drowsiness, imbalance, 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.
Sound that occurs beyond human hearing (about 20 kHz) is considered ultrasound. Animals such as dogs, cats, dolphins, and bats can hear ultrasound. Some whales and dolphins use ultrasound to detect their prey and as a weapon to stun them. It is said to be less effective as a weapon because it doesn’t retain its frequency when it couples with matter such as a human body.
Ultrasonic weapons produce a variety of effects depending on the power level and frequency. Many are the same as those produced by infrasound, plus heating and burning. They include: tickling in the mouth/nose area, discomfort, heating of the skin, nausea, abdominal pains, and vomiting. At higher decibels it causes burns and heating of body up to lethal temperatures. Another very painful effect is bone resonation, which could cause a person’s bones to literally explode.
“Aimed at the head, the resonating skull bones have caused people to hear voices,” revealed the Federation of American Scientists in their 1997 article, Non-Lethal Weapons for Military Operations other than War.
