For good muffler design it is advisable to use an advanced computational method such as four-pole theory or FEM or BEM. To get a starting points for these methods and to suggest adjustments to the geometry and materials it is useful to have some simple rules of thumb. This paper presents a number of such "rules", and illustrates their reliability and limitations by comparing with results using some of the advanced computational methods. At the same time, this investigation also gives a comparison between four-pole theory and BEM.
