Waterhouse修正及其在空气声隔声测量的应用研究

从空气声隔声量的测量原理出发，讨论声强法与声压法两种测量方法在低频段的隔声量测量结果偏差，指出在对两种方法的测量结果进行对比时须考虑Waterhouse修正项。对不同容积房间的Waterhouse修正项计算结果显示，在接收室容积较小的情况下，采用完整项的Waterhouse修正以减小两种方法在低频范围的偏差。

The application of Waterhouse correction in the measurement of airborne sound insulation

The measuring principle of airborne sound reduction index was introduced. The error between the measured sounds in the low frequency (reduction index bias) between the conventional sound pressure method and the measurement method based on sound intensity was discussed. Waterhouse correction was employed to compare the results between the two methods. The results of Waterhouse correction for rooms in different volumes were obtained. The results show that the complete term of Waterhouse correction would reduce the low frequency errors between the two methods.
