A sonic weapon is a device that uses sound waves to incapacitate or deter individuals. These weapons can emit high-frequency sounds or loud noises that can cause discomfort, disorientation, or even pain. They are often used in crowd control situations by law enforcement or military personnel. Sonic weapons can vary in design and function, with some examples including the Long Range Acoustic Device (LRAD). This technology is designed to project sound over long distances, allowing for communication or deterrence without physical contact. The use of sonic weapons raises ethical and legal questions regarding their impact on human health and rights.
