Book Summary

A theoretical treatment of sound transmission through the walls of non-circular muffler shell is done for plane mode transmission within the muffler shell. Non-circular muffler shells include distorted circular (due to the welding seam), elliptical (oval) and flat-oval shells. An analytical formulation has been developed in this thesis in order to predict the breakout noise with the acoustical and structural wave coupling phenomena. First, progressive wave model is chosen. Then, the Transverse Transmission Loss (TTL) is predicted at different frequencies of interest. This formulation is extended to the standing wave model by which results for anechoic, rigid end and open end boundary conditions are obtained.
