In today’s world where the technologies are emerging at high speed and also new regulations and standards for noise emission increasing in the automotive firms and hence there is need to think over the current working system for the noise reduction or to make some improvements about decreasing the engine noise. Nowadays, the perforated reactive mufflers which have an effective damping capability are specifically used for this purpose. In this work new designs should be analyzed with respect to both acoustics and back pressure. In this study, a reactive perforated muffler is investigated numerically, experimentally and by the analysis. For an acoustical analysis, the transmission loss which is independent of sound source of the present cross flow, the perforated muffler was analyzed. To be able to validate the numerical results, transmission loss was measured experimentally. Back pressure was obtained based on the flow field analysis and was also compared with experimental results. Numerical results have an approximate error of 20% compared to experimental results.
