"Screamers" are a type of sound-based weapon designed to incapacitate or deter individuals through loud, piercing noises. They are often used in military and security contexts to create confusion and panic among adversaries. The sound produced can be disorienting, making it difficult for targets to think clearly or respond effectively. These devices can be triggered by motion or remote control, allowing for strategic deployment in various situations. While they are primarily intended for non-lethal purposes, the intense noise can cause temporary hearing loss or psychological distress. Screamers are part of a broader category of non-lethal weapons, which also includes items like stun grenades and tear gas.
