Abstract

This paper shows the details of measurement of the Acoustic Transmission Loss evaluation with circular inlet and tail pipe with nozzle shaped muffler configuration. This configuration analyzed by using Finite element Analysis (FEA). For these purpose the evaluation of transmission loss of different nozzle shape of tail pipe has been simulated by keeping constant volume of Expansion chamber. Also the design validation has been done with the existing results with same dimension to prove the compatibility of acoustical simulation. To observe the effect of transmission loss of circular cross-section expansion chamber with introduction of various nozzle shape tail pipe at by analyzing in FEA Acoustic Module. After the observation the results are compared in order to observe the effect of introduction of nozzle shape outlet in muffler.
