Flashbang (Stun grenade) by 3borg

A stun grenade, also known as a flash grenade, flashbang or sound bomb,[1] is a non-lethal explosive device used to temporarily disorient an enemy's senses. It is designed to produce a blinding flash of light and an intensely loud "bang" of greater than 170 decibels (dB)[2] without causing permanent injury. It was first used by the British Army's SAS in the late 1970s.[3]
