Acoustic Hailing Device

Product Code: AA76825
Acoustic Hailing Device
The AA76825 Acoustic Hailing Device, also known as Long Range Acoustic Device LRAD, is the loudest acoustic hailing device in production (world’s first +160 dB directed voice projection system), and is the ideal sound solution for communicating extremely long distances and penetrating high background noise environments (such as airplanes, helicopters, sirens, vehicles, and boisterous crowds) to ensure unmistakable commands.
 
With an acoustic footprint in excess of 2000 meters and a narrow acoustic beam of +/-5°, clear, intelligible messages and authoritative commands are broadcast to intended targets. Determining intent and influencing behavior, the AA76825 Acoustic Hailing Device can produce a warning tone of 135 dB at 100 meters. A powerful built-in warning tone projects an attention-getting, high frequency warning which enhances military and security personnel’s response. Piercing alert tones are heard loudly and clearly. This non-lethal deterrent tone is highly irritating. It can be compared to a water cannon, but with sound.
 
Using breakthrough technology, the AA76825 Acoustic Hailing Device can accurately reproduce sound with less than 1% distortion across the entire wide frequency range. With a STI rating of 0.91 out of 1.0, this device produces clear and authoritative voice output at range. Equipped with pan and tilt capability, the AA76825 Acoustic Hailing Device is the clear choice for large scale ships and platforms with the longest range requirements.

The technology behind the Acoustic Hailing Device (Long Range Acoustic Device LRAD) was developed to support the protection and exclusion zones around U.S. Navy warships following the October 12, 2000 small-boat terrorist attack on the USS Cole off the coast of Yemen killing 17 sailors and causing $240 million in structural damage to the $1 billion ship. Acoustic Hailing Devices are currently used around the world on sea (military, private and commercial vessels), on ground (tanks, armored vehicles, military/police vehicles, structures), and in the air (helicopters).
