A Review on Muffler Design for Exhaust Noise Attenuation

Abstract

The pressure waves escape from the engine exhaust with a high velocity producing an offensive exhaust noise. A properly designed exhaust silencer is helpful to reduce exhaust noise. In these review paper different types of mufflers and a performance characteristic of muffler have been studied. In designing, different parameter which has been to taken into the consideration. These parameters affect the muffler efficiency. This paper also focuses on sound attenuation, back pressure which is most important criteria for selection of muffler.
