A suppressor, sound suppressor, sound moderator or silencer is an accessory device that is attached to or part of the muzzle of a firearm or air gun’s barrel and reduces the noise signature (muzzle report) and visible flash generated by the gun’s firing.
Suppressors are typically constructed of a metal cylinder with internal baffle components to slow and cool down the escaping propellant gas and thus decrease the sound intensity of the muzzle blast.
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, suppressors are regulated by firearm legislation to varying degrees.
Muzzle blast generated by firearm discharge is directly proportional to the amount of propellent to be combusted within the cartridge. a magnum cartridge), the louder the muzzle blast and consequently a more efficient or larger suppressor system is required.
A gunshot (the combination of the sonic boom, the vacuum release, and hot gases) will almost always be louder than the sound of the action cycling of an autoloading firearm. Paulson, a renowned firearms specialist, claimed to have encountered an integrally suppressed .22 LR that had such a quiet report, Cross-section drawing of a BR Tuote rifle suppressor, showing expansion chamber "reflexed" (going back around) the rifle barrel, and four baffles.
The earliest use of the term "suppressor" to refer to firearm noise reduction is in US Patent 4530417, July 23, 1985 "A suppressor for reducing the muzzle blast of firearms or the like.".Vented barrel surrounded by metal mesh packing in expansion chambers, followed by conical baffles in forward chambers The suppressor is typically a hollow metal tube manufactured from steel, aluminium, or titanium and contains expansion chambers.This device, typically cylindrical in shape, attaches to the muzzle of a pistol, submachine gun, or rifle.The chambers are divided by either baffles or wipes.There are typically at least four and up to perhaps fifteen chambers in a suppressor, depending on the intended use and design details.
