Acoustic Analysis of Single Expansion Chamber Reactive Muffler - A Critical Review

Mahesh Kulkarni, Sahil Jadhav

Abstract: Internal combustion engines, in particular, contribute significantly to societal noise pollution. Mufflers are typically used at the end of an exhaust system to reduce noise. The muffler's components' design and use determine how well it lowers noise. As a result, it is critical to design mufflers that reduce noise to the greatest extent possible. In this study, the Transmission Loss (TL) of a single expanding chamber reactive muffler will be measured utilizing a variety of approaches. The Acoustic Examination of the Silencer is carried out using three methods: theoretical analysis, finite element approach using COMSOL Multi - Physics, and experimental analysis using the two - load method.
