摘要
阐述了声强法的测量原理,简要说明了如何用声强法进行噪声测量以及根据测量结果对产生噪声的具体位置进行识别。通过对某型发动机进行声强测量研究,得到了该发动机声强云图和噪声分布情况,并确定了主要噪声零部件及其辐射特性。
This paper expatiated the principle of sound intensity measurement, and simply explained how to measure noise with sound intensity measurement and identify the concrete position of noise according to the measurement results. To a certain engine, the paper carried on a sound intensity measurement research,got the sound intensity cloud diagram and noise distribution of the engine,and found the main parts of noise source.
