Acoustic weapons are devices that use sound waves to incapacitate or deter individuals. They can produce loud noises or focused sound waves that can cause discomfort, disorientation, or even physical harm. These weapons are often designed for crowd control or military applications, utilizing sound frequencies that can affect human hearing and balance. Some examples of acoustic weapons include the Long Range Acoustic Device (LRAD) and various sonic crowd control systems. These technologies can emit sounds at specific frequencies to target individuals or groups, making them a non-lethal option for law enforcement and military operations. However, their use raises ethical and health concerns.
