LRAD’s omnidirectional ONE VOICE® systems combine warning sirens and highly intelligible voice broadcasts to provide advanced mass notification and public address solutions. Antiquated warning systems sound sirens to alert of approaching danger, but most are incapable of clear voice broadcasts containing critical information about the severity of the situation and recommended actions to protect and save lives. LRAD mass notification systems are also used to communicate to crowds during large, outdoor events and to affected populations throughout emergency situations. LRAD systems are self-contained or easily integrated with existing communications infrastructure.
