Silencer (silver) and exhaust pipe on a Ducati motorcycle A silencer cut open to show the insulation, chambers and piping inside the shell. A muffler (North American and Australian English) [1] or silencer (British English) is a device for reducing the noise emitted by the exhaust of an internal combustion engine—especially a noise-deadening device forming part of the exhaust system of an ...
A silencer, also known as a sound suppressor, suppressor, or sound moderator, is a muzzle device that suppresses the blast created when a gun (firearm or airgun) is discharged, thereby reducing the acoustic intensity of the muzzle report (sound of a gunshot) and jump, by modulating the speed and pressure of the propellant gas released from the ...
It frequently has a larger pipe than the rest of the exhaust system. This produces a final reduction in pressure and is sometimes used to enhance the car's appearance. In the late 1950s, in the United States, manufacturers had a fashion in car styling to form the rear bumper with a hole at each end through which the exhaust would pass.
However, suppressors work on a different principle, not by vectoring the gas expansion laterally but instead by modulating the forward speed of the gas expansion. By using internal baffles , the gas is made to travel through a convoluted path before eventually released outside at the front of the suppressor, thus dissipating its energy over a ...
The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) made a regulatory determination in 2013 that the muzzle device of the SIG Sauer MPX Carbine, adapted from the baffle core of the integrally suppressed version's suppressor and claimed by SIG to be a muzzle brake, constituted a silencer and rendered the MPX-C a Title II NFA weapon.
Animation of the Vickers muzzle booster operation, showing the expanding gases pushing the barrel to the rear relative to the cooling jacket. A Vickers-type muzzle (or recoil) booster, the "typical" type, consists of two parts: a flared "cup" on the muzzle of the barrel, and a perforated tube around the end of the muzzle, attached to the main body of the weapon.
The National Transportation Safety Board has recommended that all new automobiles come equipped with technology meant to make speeding difficult or impossible, a move that comes after an accident ...
The Wikipedia argument for why suppressor is more "correct" is that silencers do not eliminate 100% of noise, but that is not how English works. The UK English term for muffler is silencer, with no regard for the obvious fact that car silencers/mufflers do not make cars "silent". Worse, any dictionary can confirm that "suppress" does not imply ...
