When starting the design of a muffler, the attenuation characteristics to be muffled must be prepared in advance. It is intended, in this report, to study a method to find the attenuation characteristics through calculation. In this paper, firstly the author has studied about the desirable standard level for designing an exhaust muffler, and secondly about the method of converting the sound pressure of the desirable noise level and the exhaust noise to power level, and then a whole system for designing a muffler was shown in various steps. Finally, an example of calculation for a real engine was presented.
