Computational analysis of transmission loss in an exhaust muffler / Mohd A 'zmi Yunus, Ahmad Azlan Mat Isa and Mohamed Dahalan Mohamed Ramli

Mufflers are commonly used for automobile exhaust system to attenuate the noise levels produced by automobile engine to the atmosphere. Since the muffler becomes an important part in automobile exhaust system a restrictive environmental legislation requires silencer designers to use high performance...

description Mufflers are commonly used for automobile exhaust system to attenuate the noise levels produced by automobile engine to the atmosphere.
