The theoretical analysis of the exhaust muffler of an internal combustion engine contains various difficult factors. Almost all the studies on the attenuation characteristics of a muffler are an analysis based on the assumption that the tail tube is inhite in its length. But, from the practical point of view, the author considered the following points in order to induce a theoretica1 formula made to resemble the practical situation as closely as possible. a) The length of a tail tube is finite. b) The exhaust noise contains the sound radiated from the ejecting gas. c) The exhaust gases have some gradient in each exhaust system. On the other hand, he set some mufflers to an engine and conducted some experiments to compare the calculated value with the measured one.
