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 sound attenuator, or duct silencer, sound trap, or muffler, is a noise control acoustical treatment of Heating Ventilating and Air-Conditioning (HVAC) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces in a building, or between occupied spaces.
More generally, it refers to "any of various devices used to muffle or soften the tone of an instrument". [2] The act of using a mute is called "muting". [2] Brass mutes are occasionally referred to as "dampers", [2] but "damping" usually means reducing or deadening the sound after it has been played. [3]
Use of multiple strips causes a heavier muffle. Taping a tissue or napkin to the rim of the drum, and letting it lay loose on the batter head. Again, different thicknesses and positions create different sounds. For toms and snares, moongel can be used to reduce overtones. The bigger the piece of gel, the more the sound is muffled.
A pair of headphones being tested inside an anechoic chamber for soundproofing. Soundproofing is any means of impeding sound propagation.There are several methods employed including increasing the distance between the source and receiver, decoupling, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles for absorption, or using ...

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 ...
Transmission loss (TL) in duct acoustics describes the acoustic performances of a muffler-like system.It is frequently used in the industry areas such as muffler manufacturers and NVH (noise, vibration and harshness) department of automobile manufacturers, and in academic studies.
