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 ]
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 ...
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 ...
AN/SQS-53 is an improved version of AN/SQS-26CX. The main difference between the SQS-26CX and SQS-53 sonars is the digital computer interface with the Mk 116 anti-submarine warfare (ASW) weapon control system in the latter. [4] In addition, AN/SQS-53 sonar can be fitted with the Kingfisher small obstacle (mines) avoidance sonar. [4 ...
The science of long-range sniping came to fruition in the Vietnam War. US Marine Gunnery Sergeant Carlos Hathcock held the record from 1967 to 2002 at 2,286 m (2,500 yd). [12] He recorded 93 official kills. [citation needed] After returning to the US, Hathcock helped to establish the Marine Corps Scout Sniper School at Quantico, Virginia. [13]
As the gunfire pops off, the videographer, along with the entire crowd, makes a mad dash for safety, the footage shows. “Oh s–t! Oh hell no!,” the man recording shouts.
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.
Ukrainian President Volodymyr Zelenskyy said Thursday his country has developed a weapon that hit a target 700 kilometers (400 miles) away, in an apparent reference to the previous day’s strike ...
