Optimal Determination of Transmission Losses for Hybrid Absorptive Mufflers under Space Constraints using Different Absorptive Materials

Abstract

In this research work, a muffler has been designed using the finite volume method, and the results have been proven by making an experimental setup to validate its design. After this, in the research work, a muffler of the same dimension was designed using the finite volume method and by making changes in its design, like installing a baffle and making perforations in its pipe based on different flow percentages, and finally, the optimum muffler design was found. The last enhancement in sound transmission loss was seen by filling different sound-absorbing materials inside the muffler design at different densities.
