Aug 10, 2017 · Infrasound doesn’t need to be heard for it to work. Since the 1990s, the US military and private companies researched infrasonic devices that could cause behavior changes at frequencies too low...

Jul 30, 2012 · 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 …

Sonic and ultrasonic weapons (USW) are weapons of various types that use sound to injure or incapacitate an opponent. Some sonic weapons make a focused beam of sound or of ultrasound; others produce an area field of sound. As of 2025, military and police forces make some limited use of sonic weapons.

Acoustic weapons, also known as long-range acoustic devices and sound cannons, are devices that deliver very loud sounds over long distances. This technology is used for crowd-control purposes by emitting loud and painful levels of noise that may lead to significant harm to the ears, potentially causing hearing loss. Serious questions remain ...

Infrasonic weapon: This newer technology is under investigation. It would deliver very low-frequency sounds that would be inaudible but could cause pain, disorientation, nausea, and possibly long-term hearing loss. There is little medical literature on the effects of acoustic weapons on people.

Jul 5, 2018 · Infrasonic defensive armaments could now be safely directed away from the operators against any foe. This weapon was a remarkably compact and efficient device. Its efficiency was gauged by the destructive output and the weapon volume. A later embodiment of this terror disclosed another compact cube. The infrasonic whistle was presumably housed ...

Sep 25, 2019 · A new weapon invented by Chinese scientists uses low frequency sound waves to cause physical distress, forcing rioters, protesters, or anyone else the wielder wants to vacate the area.

Jan 2, 2025 · 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.

Nov 21, 2012 · The low frequency of infrasonic sound and its corresponding long wavelength makes it much more capable of bending around or penetrating your body, creating an oscillating pressure system.

Aug 9, 2017 · Infrasound has been utilised as a means of sonic warfare for physical human impact, dating back to World War 1. Acoustic imaging was the primitive use of infrasonic sound during World War 2, for the use of radar and sonar techniques in order to detect locations of enemy artillery (Ihde, 2015).
