| 摘 要： | 针对原铁路噪声比例预测法不适应铁路提速和环境变化的需要,对其方法进行了改进。改进后的比例法采用现场实测的暴露声级作为输入参数的噪声基本量,可以按货运列车、常速列车、提速列车、客运专线列车等分类。提出的修正量参数适应由于列车、车辆技术改进或更新所引起的噪声辐射强度的变化。

| Abstract: | The original proportional prediction method adopted to predict railway noises was modified in this paper because it could not suit for the noise prediction when trains speed was increased. This modified method uses exposure sound level (LAE) measured on the spot as basic noise data for input, which can be typed into freight trains, trains at normal speed, trains at higher speed and special trains for passenger, etc. The modified factor proposed can be adapted for the changes of noise intensity caused by technical improvement of trains or cars. |
