LRAD - Next Generation Communication for Fire Rescue Teams
When fire rescue and emergency management teams need to communicate critical information to individuals or groups in harm’s way, LRAD systems broadcast audible voice messages with authority and exceptional clarity from close range out to 3,500 meters. LRAD systems are being used by public safety agencies around the world to ensure critical information and potentially lifesaving directions are clearly delivered, heard, and understood. Unlike conventional loudspeakers, bullhorns and outdoor P.A. systems that disperse sound in all directions and have limited loudness and poor vocal quality, LRAD’s proprietary driver and waveguide technology focuses sound in a 30° beam while substantially reducing sound levels behind the long-range communication systems and in surrounding areas. Up to 10X louder than most bullhorns and vehicle P.A. systems and significantly more intelligible at any distance,
LRAD is optimized to the primary human hearing range of 1–5 kHz to ensure every LRAD broadcast is clearly heard and understood over engines, sirens, and background noise.
