混响室内声功率发射的实验研究

Experimental investigation on sound power emission in reverberation chambers

本文简要论述了马大猷教授用简正波理论分析混响室内声功率测定问题所提理论。对位置函数Ｆ（ｄ）进行了实验研究。证明位置函数确实存在。理论与实验结果符合甚好。本文最后提出了进一步的实验设想。

The theory of sound power determination in reverberation chambers derived from the normalmode, proposed by Prof. Maa Dab-You, is brieny elaborated. Experimental investigations on the positionfunction F(d) had been carried out. It proves that the posion function F(d) exists in reality. The theory agreewell with experimental results. Finally, further designs of experimental investigation are proposed.
