ABSTRACT

The sound quality of any product plays an important role for its marketing and popularity. Here in this research we are trying to improve the sound quality of passenger car. So for the sound quality of car, we are trying to modify the exhaust system.In the exhaust system, are using baffle plate with perforation. Firstly we use single baffle with perforation and increase the baffle plate up to three baffle plates.This project deals with four different models of chambered exhaust muffler with perforation in baffles and concludes the best possible design for good sound quality. In this exhaust system along with baffles plate, we also use absorptive materials to improve the sound quality. Absorptive materials for this research we are using the glasswool and rockwool. For this research we have performed all the simulation in Ricardo wave build software. So after simulation in Ricardo wave build software, we conclude that the muffler with having three baffle plate along with rockwool as an apsorptive material give the best result as compare to other cases.
