Acoustic weapons, also known as long-range acoustic devices and sound cannons, are devices that deliver very loud sounds over long distances. In one mode, the LRAD acts as an amplifier, projecting a human voice or recording across thousands of meters; in the other, it emits a deterrent tone so loud it can cause permanent hearing loss. From the curators: Acoustic Hailing Devices (AHDs) are specialized loudspeakers that emit high-power sound waves enabling clear communication at long distances.
