Analyzing Muffler Performance Using Transfer Matrix Method

Noise pollution created by engines becomes a vital concern. The main source of noise in an engine are the exhaust noise and the noise produced due to friction of various parts of the engine. The exhaust noise is most dominant. To reduce this noise, various kinds of mufflers are used. Muffler plays an important role in reducing the exhaust and intake system noise and as a result, a lot of research is done to design these systems effectively. The traditional "build and test" procedure, which is time consuming and expensive, can now a days, be assisted by numerical simulation models. In this book various methods of design, analysis and experimental investigations of mufflers have been done.
