The one-dimensional (1-D) time-domain approach and the three-dimensional finite element method (FEM) are used to predict and analyze the acoustic attenuation performance of three-pass perforated tube mufflers with and without end-resonator. For the given muffler configurations, the transmission loss results obtained from the 1-D time-domain approach agree reasonably well with the FEM predictions within the plane wave region, while the 1-D results derive the FEM predictions at higher frequencies. The FEM is then used to investigate the effects of internal structure on the acoustic attenuation performance of the mufflers, while the 1-D time-domain approach is employed to examine the influence of high temperature gas flow on the acoustic attenuation performance of the mufflers within the plane wave region.
