Flowmaster Ltd. was a leading British Engineering Simulation Software company based in Towcester, UK. Its flagship 1D CFD product, also named ‘Flowmaster’, was first released commercially in 1987 although initial versions went back to the early 1980s having originated from BHRA, the not-for-profit British Hydromechanics Research Association, later to become the BHR Group.
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.
Whistle tips, also referred to as whistler tips, or whistlers, are modified vehicle exhaust pipes that generate a whistling sound during the operation of a motor vehicle that can often be heard up to a mile away. [1] The whistle tip is a small metal plate with a central hole that is welded into the inner tip of the exhaust pipe.
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 ...
The glasspack is an old, simple, and relatively inexpensive muffler design that has less back pressure than other types of muffler, but is less effective at muffling noise. A longer glasspack will reduce noise to a greater extent than a shorter one, as sound is dissipated into the fiberglass damping material.
