Infrasound Weapons: Silent But Deadly

Updated on July 30, 2012

The range of human hearing is quite limited. This is not a revelation to most people, as it is common knowledge that animals, including our household pets, are able to perceive frequencies of sound beyond that of their human owners. In fact, dog whistles and certain types of "invisible fences" are practical applications of this knowledge. These devices operate at a higher frequency than humans can audibly perceive, however, there is also a bottom threshold to human hearing, which is about 15 cycles per second. The area below this frequency is known as infrasound. Although infrasonic frequencies cannot be heard by people, they can be felt. Perhaps you've experienced pressure or vibrating in your chest generated by powerful subwoofers blasting out bass lines at a concert.

At greater intensities, infrasound can make a person feel ill and disoriented. At even greater energies, infrasound can kill by causing the internal organs of a person to vibrate so violently that they rupture. Obviously any device that could generate infrasound at these energies would make a devious and lethal weapon.

The reason sound waves can kill is that they carry energy. The sound waves caused by a powerful thunderclap, though miles distant, can not only startle a person, but can rattle dishes in cabinets and knock knick-knacks off shelves. That is because the sound waves still carry enough energy to disturb physical objects despite traveling such a distance.

In 1957, while the Cold War was still quite heated, Dr. Vladimir Gavreau had assembled a team of researchers dedicated to developing robotic devices for a variety of military and industrial purposes. During work, the team would periodically fall victim to spells of nausea. Even those called upon to inspect the facility to determine the cause would experience the same ill feeling. Strangely, whenever the afflicted person or persons would step outside the building, the symptoms vanished. They found that opening the windows reduced the effect, but not did not eliminate it entirely. The mystery affliction persisted, causing a serious disruption of Gavreau's work. Eventually, after other causes such as noxious vapors or compounds were ruled out, the culprit was determined to be a ventilation fan motor. Gavreau's team knew the fan motor was the culprit, as direct exposure to it caused its victim to be ill for hours afterward, but they did not know why.

The motor was causing vibrations of the air at 7 cycles per second, well into the infrasonic range. The sound from the fan motor could not be heard, but its effects were quite evident. Eventually they determined the infrasonic waves from the motor caused a resonance within the building. A resonance occurs when the frequency of sound is just right so that the peaks and troughs of the sound waves bouncing back and forth in a medium line up and reinforce each other. Thus, the peaks are higher and the troughs are deeper. The cavernous interior of the industrial building amplified the sound waves even more. When the thoughts of the group turned toward reproducing the effect through some type of self-contained, movable apparatus, the potential for weaponization became obvious. Experimentation produced a device utilizing large custom-built organ pipes, with the energy supplied first by a motor-driven piston, then by a pneumatic mechanism.

Dr. Gavreau's team tested the infrasonic device on themselves. The effects were almost immediate. First came intense pressure on the eyes and eardrums. Soon after, intense pain racked the entire body. Then the entire building, a massive and stout concrete structure, was shaken. One of the team members managed to switch off the power, despite being in excruciating pain. The group experienced altered vision and painful spasms throughout the body for days following that one brief test. In retrospect, it seems that if the device had been left on any longer, Dr. Gavreau and his team would have died right there and then, victims of their impatience to have empirical data on the effect of their new endeavor on living human beings. The team had also seriously miscalculated the power that would be generated by their device.

Earlier I referred to infrasonic weapons as both lethal and devious. The devious nature is derived from the fact the weapon makes no audible sound. A soldier approaching a defense perimeter using infrasonic weaponry would have no advance warning that he or she was walking into a death trap. Additionally, sounds at such low frequencies pass easily through solid objects, such as concrete walls.

Given the rapid proliferation of atomic weapons following WWII, one might expect to have seen in the years following Gavreau's discovery battlefield ready infrasonic weapons capable of slaughtering entire opposing armies, without warning and without the firing of a single bullet. It is surprising therefore, at least on some level, that infrasonic weapons of deadly capability have apparently never been used outside of an experimental setting.

Could it be that the superpowers of the East and West had conscientious objections to using such a stealthy but brutal weapon? Or were they afraid of tipping the balance of power that Mutually Assured Destruction maintained? These days we do not fear hydrogen bombs and ICBMs launched by the Soviets, rather we fear suitcase nukes and low-tech dirty bombs in the hands of terrorists and extremists. Considering a handful of scientists were able to build an effective infrasonic weapon out of oversized organ pipes and a simple air-compressor, would duplicating this really be outside the capability of a terrorist group or other rouge entity? Perhaps we should just be thankful that it appears there is little interest in weaponizing sound in such circles and Gavreau's weapon is relegated to being another obscure historical curiosity.

      I have neighbors who make no effort to hide their dislike. This morning my blood pressure wake up was 190 over 107. Clearly they are slowly trying to kill me. I hear nothing and live in detached housing very close to them. Suffering infrasound through the night will increase cortisol production.

      Can hardly walk because of hbp. Perhaps microwave used in conjunction. How can I measure this and why is it my son upstairs is not effected.

      @ Tony C. I feel you brother, currently living the nightmare you describe with my neighbor as well. Floor slightly vibrating. Can't sit in a chair without it slowly swaying slightly side to side. I hear something, it doesn't sound quite like music but rather like someone recorded industrial noises and play the soundtrack on low as my floor vibrate slightly. I have even heard a slight tune when I turn on the courtesy fan in the restroom. You're right it's hard convincing people these subwoofers are versatile weapons of harassment but they are.

      Infrasonic weapons are actually as described. This is because, what is visible is the physical disastrous, calamitous, devastated destruction caused by its effect. And this is also despite its non-audible and non-visible nature, due to its being within and at the lower levels of the Sonic/Acoustic/Sound Spectrum.This is the extent the Homo Sapiens have carried their researches into effective deadly weapons of destruction.

      I have also experienced this infrasound assault just this past week (1/24/2015-1/31/2015 so far). I don't think it's the government though, it's my neighbors! (Maybe they know someone in the government?) I believe somehow he's turned his loud, noisy, rude subwoofers into silent sound waves. I have been awakened every night by vibrations but there's no acoustics. Nothing mechanical banging around, no sound whatsoever. It feels like my bed is next to an idling SUV. Good luck to you Darren on finding the source and hopefully putting an end to it.

      REVISED 11-20-14

      My name is Darren M. and I believe I am being targeted with concentrated infrasonic sound waves while I attempt to sleep at night. I believe I am being targeted for D.E.W. (directed energy weapon) experimentation/harassment purposes by an entity within the U.S. government employing private contractors to carry out this experimentation/harassment.

      I am awakened many times throughout my sleep periods to a feeling of vibrations traveling through my body in a straight line. The vibrations are focused in a narrow beam. It is impossible for me to stay asleep when I am targeted with these inaudible concentrated sound waves which increase my pulse rate as they travel through me. Different parts of my body are targeted at different times. When my head is targeted I will awake with moderate to severe headaches. I have also experienced head spins to the point that I had to lift my head up out of a lying down position to make them stop. When my chest area is targeted, I will awake with rapid or irregular heartbeats. In addition, I experience sleep deprivation on a nightly basis due to the repeated forced awakenings. The private contractors that target me hit me every 1-2 hours on average during the first part of my sleep period, and they increase the frequency of their targeting to every 15-30 minutes during the 2nd part of my sleep period. I fear that I will lose my job and become homeless due to the sleep deprivation that this experimentation/harassment has caused me. I also fear that my health will deteriorate.

      I want to make sure that my story is told in the event this experimentation causes my premature death. I also want to make sure that potential future victims do not suffer the way I have from these silent sound wave weapons. I don’t believe anyone can help me because of my failed attempts to provide proof of this experimentation and the apparent disbelief and disinterest of the authorities in the U.S.

      Thanks for the love. I corrected a few errors, including using "ultrasound" a few place where I meant "infrasound."
