Abstract:

Noise produced by exhaust of an IC Engine, is one of the main cause of noise pollution in today’s environment. With the increase in vehicles at alarming rate, it has become necessary to have an effective noise-attenuating device to control this noise pollution. Muffler is one of such device that can be used for noise reduction. Transmission loss is the major performance parameter of muffler and it depends on the acoustic filters applied to it. This paper reveals the performance of transmission loss on using perforated tube as an acoustic filter. Different parameter of the perforated tube such as perforated whole diameter, porosity and dimension of the tube are considered for study. All the analysis for the evaluation of transmission loss is performed by using ANSYS which is one of the major CAE tool for simulation. The paper also reveals new models that have better sound attenuation capabilities than the conventional model especially at low to medium frequencies level.
