工厂噪声对厂外环境的影响预测方法及实例计算

Forecast method of noise impact on outside environment by a factory and instance calculation

本文论述了工厂的室内和室外声源的几种传播计算模式，指出了具体的计算方法和简化办法，并用具体实例进行了演算，还将计算结果与监测结果进行了比较。

In this paper,the author discusses several calculation modes of noise propagation within and outside the workshop of a factory,and indicates concrete calculation methods and their simplified formulas. Moreover,the author also carries out demonstration with real instance,and compares the calculation results with monitoring data The comparison proves that those methods are practical in noise forecast
