摘要： 为了研究350 km/h 高速列车运行状态下噪声随距离衰减规律，对已开通运行的京津城际铁路列车运行时辐射噪声进行测试与分析，得出京津城际铁路噪声随距离衰减规律。结果表明，在高架桥路段（桥墩高6 m），距离60 m处噪声达到最大，在60 m以后，噪声开始衰减明显。其研究结果对今后高速铁路降噪设计具有一定的参考价值。

Abstract: In order to investigate the noise level of different line forms of 350 km/h high-speed train, the noise intensity at different distance from the Beijing-Tianjin Inter-City high-speed railway was tested and analyzed. The result indicates that the noise level radiated by the train reaches the highest at 60m distance. Then the noise level decreases with the distance increasing. The result is significant for noise reduction design of the express train-sets.

Key words: vibration and wave, high-speed train, noise, decreasing
