Abstract
Numerical analysis technique for three dimensional sound fields including perforated plates, by boundary element method is proposed. This technique is useful to design sound absorption structure of perforated plate efficiently. To verify validity of the numerical analysis method, the sound field in the acoustic tube in which perforated plate was installed to be slanted was predicted, and the result was compared with experiment. The sound absorption coefficient and the sound pressure distribution on the perforated plate by this numerical analysis agreed with experiment result. In conclusion, the accuracy of the proposed method is high enough and the method is useful for designing sound absorption structure using perforated plate.
