In Vietnam, U.S. forces turned sound into psychological warfare.
How does an LRAD work?
An LRAD is a loudspeaker-like device that emits a focused beam of sound. What makes these systems unique is that rather than transmitting sound like a loudspeaker in many directions (similar to the way a lightbulb emits light), LRAD systems transmit sound in a narrow beam (much like a flashlight).
What is an LRAD cannon?
The Long-Range Acoustic Device (LRAD) is an acoustic hailing device, sound cannon and sonic weapon developed by Genasys. LRAD systems are used by law enforcement, government and defense agencies, as well as maritime and commercial security companies to broadcast audible notifications and warnings over distance.
