摘要
相位失配误差是声强测量系统的主要误差源，仅靠提高仪器的精度很难消除这一误差。文章提出了一种简单易行的修正声强测量系统相位失配误差方法。理论分析和实验验证表明该方法操作简单，修正准确可靠。
The phase mismatch error is the main error source of sound intensity measurement system. It is difficult to eliminate this error only by upgrading the accuracy of instrument. In this paper, A simple method to correct the phase mismatch errors of Sound Intensity Measurement System is developed. The accuracy and efficiency of the method have been proved by the results of theoretical analysis and experiment test.
