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 ...
This lower flow but slightly quieter design approach is commonly used in glasspack mufflers. Some modern muffler designs are similar in principle to the glasspack, but use more sophisticated sound-absorbing materials such as stainless steel mesh, and more advanced acoustic engineering, reducing noise while retaining the power-preserving ...
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.
Rolls-Royce Conway Mk508 (1959) with hush kit attached. The most common form of hush kit is a multi-lobe exhaust mixer.This device is fitted to the rear of the engine and mixes the jet core's exhaust gases with the surrounding air and a small amount of available bypass air.
Noise control for aerodynamic sources include quiet air nozzles, pneumatic silencers and quiet fan technology. Since many mechanical sounds are inherently loud, the principal design element is to require the wall or ceiling assembly to meet certain performance standards, [ 21 ] (typically Sound transmission class of 50), which allows ...
Dry January is a challenge started in 2013 to eliminate alcohol from your diet. This is what you need to know about the health benefits.
For best results, use big sea scallops and thin-cut, conventional bacon, but feel free to swap out the herbs for whatever you like. Get the Bacon-Wrapped Scallops recipe . Photographer: Lucy ...
