Acoustic Hailing Device Acoustic Hailing Device
The AA76823 Acoustic Hailing Device is a self-contained, lightweight, all weather capable, portable acoustic hailer for communicating long distances and penetrating high background noise environments. With an acoustic footprint up to 1500 meters and a narrow acoustic beam of +/-12°, the AA76823 packs a peak acoustic output of 151 dB to ensure clear and authoritative voice commands are clearly understood.
Powerful deterrent tones which enhance military and security personnel’s response capabilities are easily accessible with the built-in high frequency alert tone. This non-lethal deterrent tone can be as loud as 151 dB and is highly irritating. It can be compared to a water cannon, but with sound.
The Acoustic Hailing Device easily penetrates high background noise environments (such as airplanes, helicopters, sirens, vehicles, and boisterous crowds) to ensure unmistakable commands. Piercing alert tones are heard loudly and clearly.
Weighing only 37 pounds, the rugged, lightweight carbon fiber reinforced housing is easily transported and withstands extreme maritime and desert environments. An exceptional STI rating of 0.81 out of 1.0 combined with an extended frequency range ensures authoritative voice commands are clearly delivered to the intended target.

The technology behind the Acoustic Hailing Device 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).
