| Abstract: | In order to make Prof. Maa's accurate theory be applied in practice as soonas possible, in this paper, the computer aided design of miicroperforated -panel sbaorber based on the acctuate theory is made. In addition, some problems, therelation between the structural parameters and the properties of sound absorption, andthe design characteristics of microperforated -panel absorber at high sound intensity etc.,are discussed. |
