Estimation of the area effect of sound absorbent surfaces by using a boundary integral equation

[摘要] References(8)Cited-By(9)A method of predicting the area effect of an absorbent surface with finite dimensions by using a boundary integral equation is proposed and the reason why the area effect occurs is shown. In order to check the effectiveness of the method, some experiments are carried out in a reverberation room. These results are in good agreement with those obtained numerically from the proposed method.
