摘要
本文对声强测量的有效性作了较全面分析，为精确的声测量奠定了基础。分析结果应用于某型飞机的声强测量中，为该型飞机的降噪工作提供了可靠的数据来源。
The effectiveness of sound intensity has been analysed and the basis for preci-sion acoustic measurement has been laid in this paper. The results of analysis have been ap-plied to measuring the sound Intensity in some type of light aircraft and the reliable sources ofdafa have been provided for the noise - reduction of aircraft.
