A silencer, suppressor, sound suppressor, or sound moderator is a muzzle device that reduces the sound intensity and muzzle flash when a firearm or air gun is discharged.

A flash suppressor, on the other hand, specifically cools or disperses burning gases typically exiting from the muzzle of a carbine-length weapon, without reference to sound reduction. In most countries, silencers are regulated along with firearms.
