摘要
经典混响场公式在计算实际厅堂的稳态声压分布时存在明显的缺点，即不能反映混响声能随接收点到声源距离的衰减这一特性。本文从Ｍ．Ｂａｒｒｏｎ的室内声场模型推导出声压级分布的修正公式。
There is an obvious defect existing in classical formula of reverberation field in calculating the actual steady state sound pressure distribution in auditorium,that is,the reverberation sound energy does not attenuate with the distance from the receiving point to the sound source. In this paper,the revised formula of the sound pressure distribution is derived from M.Barron room sound field model,and the calculated result is in good agreement with simulated value by computer. [
