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 ...
The RSOV's design is based on the Land Rover Defender Model 110, having different specifications from the British Weapons Mount Installation Kit. [2] [4] The RSOV was built by the Land Rover Special Operations Vehicle Department. [6] It was also meant to be airlifted by helicopter or transport aircraft if needed. [6] [7]
The Long Range Acoustic Device (LRAD) is an acoustic hailing device developed by LRAD Corporation to send messages and warning tones over longer distances or at higher volume than normal loudspeakers. LRAD systems are used for long-range communications in a variety of applications [53] including as a means of non-lethal, non-kinetic crowd control.
It failed as a weapon, primarily because its range was not sufficient. Modern sonic weapons such the Long Range Acoustic Device (LRAD) rely on multiple loudspeaker drivers for increased sound power, and may array them in a flat plane rather than on a parabolic surface. Such weapons do not use parabolic reflectors which necessarily limit the ...
It has a total traverse range of 425mils with the T&E mechanism (traversing and elevating mechanism) and 6,400 mils without it. The maximum elevation is 100mils and the maximum depression is 250mils with the T&E mechanism. Without the T&E Mechanism, the tripod can angle the weapon at 285 mils up or 335 mils down from zero.

The following is a list of Nike missile sites operated by the United States Army.This article lists sites in the United States, most responsible to Army Air Defense Command; however, the Army also deployed Nike missiles to Europe as part of the NATO alliance, with sites being operated by both American and European military forces.
