A "Sound Cannon" is a device that emits focused sound waves to create a loud noise or to deter individuals from a specific area. It operates by using powerful speakers to project sound at high decibel levels, which can be uncomfortable or even painful for those nearby. This technology is often used for crowd control, security, and military applications. The sound produced by a sound cannon can travel long distances, making it effective for various situations. It is sometimes referred to as an acoustic weapon and is designed to be non-lethal, providing an alternative to traditional methods of dispersing crowds or managing disturbances.
