| Abstract: | Air flow muffler can change the regular of transmission and attenuation of sound, on the other hand, it can make an additional noise in muffler, that is air flow regeneration noise. Sometimes it can offset noise elimination of muffler, furthermore, it can make muffler lose efficacy. Three kinds of representive resistance mufflers were designed in this paper, and the experiments were done. The results showed that muffler structure had influence on air flow regeneration noise and noise elimination value. And the air flow regeneration noise value was estimated. Some advices were given here in the paper to structure design in order to improve the muffler. |
