The Long Range Acoustic Device (LRAD) is a sound technology designed to project high-decibel audio over long distances. It is often used for communication in emergency situations, crowd control, and maritime security. The device can deliver clear messages or warnings, making it effective in scenarios where traditional communication methods may fail. LRAD works by using a focused beam of sound, allowing it to reach targets up to several kilometers away. Its ability to produce loud sounds without distortion makes it useful for both deterrence and information dissemination. The device has been employed by various organizations, including law enforcement and military agencies, to enhance safety and security.
