The exhaust systems of internal combustion engines generate noise with a wide frequency range, including particularly strong low frequency components. In such applications, silencers can be designed to work at low frequencies by reactive acoustic elements such as Helmholtz or quarter wave resonators, terms used in reactive muffler design. Mufflers play an important role in reducing the exhaust and intake system noise and as a result, a lot of research is done to designing these systems effectively the acoustic performance of reactive muffler is investigated. New regulations and standards for noise reduction and emission compel the automobile industries to make some improvements in design of muffler for attaining desired noise reduction. The work focuses on the design of a new muffler for an agricultural tractor with the aim of containing the noise within the limits given by international standards. Further, the design modifications are to be verified for noise reduction by COMSOL Multi-physics software.
