| Abstract: | The sound absorption mechanism of microperforated panel structure is involved. On the basis of this mechanism, the microperforated panel silencers are developed to reduce the noise level in large scale kitchen fans. The conventional dissipative silencers can't be used in the situation where a spotless environment is required, but the microperforated panel silencers can overcome the disadvantage. With the application of the silencers, the overall noise level of the large scale kitchen fans is decreased by more than 18 dB(A). |
