A long-range acoustic device (LRAD), acoustic hailing device (AHD) or sound cannon is a specialized loudspeaker that produces sound at high power for communicating at a distance. It has been used as a method of crowd control , which has caused permanent hearing damage , having an extremely high decibel capacity (up to 160 dB measured at one ...
A long-range acoustic device produces a 30 degree cone of audible sound in frequencies within the human hearing spectrum (20 - 20000 Hz). An LRAD was used by the crew of the cruise ship Seabourn Spirit in 2005 to deter pirates who chased and attacked the ship. [ 3 ]
The Long Range Acoustic Device (LRAD) is an acoustic hailing device developed by Genasys (formerly LRAD Corporation) to send messages and warning tones over longer distances or at higher volume than normal loudspeakers, and as a non-lethal directed-acoustic-energy weapon. LRAD systems are used for long-range communications in a variety of ...

A tactical light mounted to the bottom rail of a rifle Tactical light and a target in a low-light environment. A tactical light or weapon light is a flashlight used in conjunction with a firearm to aid low-light target identification, allowing the user to simultaneously aim a weapon and illuminate the target. Tactical lights can be handheld or ...
The ADS works by firing a high-powered (100 kW output power) [13] beam of 95 GHz waves at a target, which corresponds to a wavelength of 3.2 mm. [14] The ADS millimeter wave energy works on a principle similar to a microwave oven, exciting the water and fat molecules in the skin, and instantly heating them via dielectric heating.
The system for creating a shock wave of sonic energy relied on the combustion of methane and oxygen, with a frequency range of 800–1500 pulses per second. The parabolic reflector was 3.2 metres (10.5 ft) in diameter. [5] It failed as a weapon, primarily because its range was not sufficient.
AN/SQS-26 was a United States Navy surface ship, bow mounted, low frequency, active/passive sonar developed by the Naval Underwater Sound Laboratory [1] and built by General Electric and the EDO Corporation. At one point, it was installed on 87 [2] US Navy warships from the 1960s to the 1990s and may still be in use on ships transferred to ...
