| 摘 要： | 通过实际测量及数据分析，认为测量现场昼夜等效声级达到 ７７７ ｄ Ｂ（ Ａ），超过了国家标准；快速列车噪声频谱分布复杂，难以治理；列车鸣笛对铁路噪声超标贡献最大，验证了铁路噪声与列车车速的关系，最后提出控制铁路噪声的建议。

| Abstract: | Ldn of testing site w as 77.7 d B( A) w hich is not perm itted by national stan dard. The frequncy spectrum of fast train is very com plex and it is difficult to control thenoise of fast train. The w histle is the m ost im portant factor affecting the railw ay noise. Therelationship betw een noise level and train velocity w as verified. The suggestion controllingrailw ay noise w as given in this article. |
