Abstract— Combustion process in the I.C. engines and exhaust process produces gaseous pollutants as well as acoustic pollutants. The pulsating flow from each cylinder's exhaust process of automobile engine sets up pressure waves in the exhaust system having average pressure levels higher than the atmospheric. The pressure waves propagate at speed of the sound relative to the moving exhaust gas, which escapes with a
high velocity producing an objectionable exhaust noise. A suitably designed exhaust muffler accomplishes the muffling of this exhaust noise. See More
