CLASSIFICATION AND STRENGTH CACULATION OF POLLUTION SOURCE ON MACHINERY NOISE

本文介绍了机械类噪声公害源的分类方法及其公害的基本防治措施．进而，简介了构成机械的几种典型部件之噪声计算方法和被污染对象所受的噪声级计算方法，以便在嗓声控制工程设计时参考之用。

The paper was written for the authors practice on which had been engaged in environmental protection and machine scientific investigation designing work and for summaring the essence of' many foreign science and technology books and periodicals. In the paper author had introduced the classification method of the noise resource and its environmental pollution fundamental prevention-cure means. It was briefly introduced the noise count way on a lot of machine parts and noise level count step on polluted object as the reference material on noise controlling engineering.
