摘要
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 。
It is focal point that studying the propagation property of steady noise from moving trains.On the basis of experimental data,the geometrical attenuation Characteristic of noise and formula about quantitative relation between noise and speed of travelling trains were obtained.
