A Firearm silencer, suppressor, sound suppressor, or sound moderator is a muzzle device that reduces the sound intensity and muzzle flash when a firearm is discharged. It can be a detachable accessory to, or integral part of the barrel. A typical modern firearm silencer is a steel, aluminum or carbon cylinder with internal sound baffles that slow and cool the escaping propellant gas, which mainly decreases sound volume.
