The acoustic attenuation performance of circular expansion chambers with extended inlet/outlet is investigated. Three approaches are employed to determine the transmission loss: (1) a two-dimensional, axisymmetric analytical solution for the concentric conยฎguration; (2) a three-dimensional computati
Expansion chambers with single-inlet and double-outlet provide desirable broadband acoustic attenuation similar to simple (single inlet/outlet) chambers and reduce the #ow noise and back pressure in exhaust systems. The present study develops a three-dimensional analytical approach to determine the
