The Long Range Acoustic Device LRAD 300X is an acoustic hailing and warning devicecomprised of a highly directional acoustic array (beam width 15°) that is designed for long-range communication and unmistakable warning. This device can issue clear, authoritative verbal commands and has the capability of following up with powerful deterrent tones to influence behavior or determine intent at great distances.

The LRAD 300X is a compact, lightweight solution for man-portable applications or use on small fast vessels, SWAT vehicles, CROWs, and vehicle mounted armor. It can be easily transported to provide security personnel long range communications and a highly effective hailing and warning capability where needed. The LRAD 300X produces highly intelligible voice transmissions over 88 dB of background noise beyond 350 meters and is capable of communicating over 1500 meters away in a benign environment. It produces a maximum continuous output of 142 dB SPL at 1 meter.

The technology behind the Long Range Acoustic Device LRAD 300X 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. Long Range Acoustic 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).
