| Abstract: | For a newly proposed silencer, an analysis was carried to the effects of following factors on its performance by simulation calculation, such as the overall dimension, structure and noise absorption material, etc. Experimental tests prove the silencer to have good performance in noise elimination, and the simulation calculation agrees well with the experimental tests. When the inlet noise level is 149 dB, the noise elimination will be more than 84 dB, indicating good performance of the silencer. |
