Company history[edit]

LRAD was founded in Utah by inventor/entrepreneur Elwood "Woody" Norris as the American Technology Corporation in 1980 (entity # 734088-0142).[3] From 1988 to early 1992 the company was inactive. Norris recapitalized the company as a Delaware Corporation in 1992.[4] In 1996, the company launched its first directed sound technology and began engineering sound solutions for the commercial, government, and military markets. In response to the October 2000 attack on the USS Cole, the company's engineering team developed the Long Range Acoustic Device (LRAD). With the introduction of LRAD systems in 2003, the company entered the acoustic hailing device (AHD) market, followed by the introduction of the omnidirectional ONE VOICE™ Mass Notifications system in 2012. Today, LRAD communication sound systems are being used around the world in diverse applications including fixed and mobile military deployments, maritime security, critical infrastructure and perimeter security, commercial security, border and port security, law enforcement and emergency responder communications, and wildlife preservation and control.
