对客货列车运行稳态辐射噪声的传播特性进行了试验研究。通过分析列车运行试验数据 ,得出列车运行噪声在一般传播条件下几何衰减特性及噪声强度与运行速度的定量关系方程
The propagation characteristics of steady-state radiated noise of passenger and freight trains are tested. Through the analysis of the train running test data, we can get the geometric decay characteristics and the relationship between the noise intensity and the running speed of train running noise under the general propagation conditions
