Long Range Acoustic Device (LRAD™): "the Sound of Force Protection"

By Port Security Blogger

Long Range Acoustic Device (LRAD™)In response to the October 2000 attack on the USS Cole, Amarican Technology Corporation™ developed and introduced our revolutionary Long Range Acoustic Device (LRAD™) and continue to expand our sound reproduction technologies and products to meet the needs of our customers and target markets.

Long Range Acoustic Device—a megaphone with unprecedented clarity and aim that can shoot compact sound waves across several hundred yards at up to 150 decibels. the LRAD is for fending off insurgents, dispersing crowds, flushing out buildings, maintaing port security, and telling people "not to come any closer," says Marine Capt. D. J. McSweeney. Thirty-three inches in diameter, the LRAD plays MP3s and prerecorded warnings in several languages and has an adjustable screeching tone. "It's very, very irritating," says American Technology's Carl Gruenler. So irritating that human-rights activists are worried about lasting hearing damage.

On November 7, 2005 LRAD was first used to foil a pirate attack on a Seabourn Cruise Line luxury cruise. The system was installed as a part of the ship's defense systems, and was activated when pirates attacked the ship with RPGs 160 kilometers off the Somali coast . The pirates failed to board the cruiser. LRAD's maritime application was realized after the 2000 attack on the USS Cole off Yemen, as a way to keep operators of small boats from approaching US warships. The system was evaluated by commercial ship operators, as a non lethal way to ward off pirate attacks. Other applications include armed unmanned surface vehicles, as international maritime law does not allow commercial vessels to carry heavy armament.
