铁路噪声已成为社会关注的重要环境问题之一。本文对列车提速后铁路噪声的频谱、日变化规律、噪声与列车流量的关系、最大值的影响因素以及噪声级与列车车速的关系等诸方面进行现场实测与分析研究,进而阐明列车噪声特性,并提出控制铁路噪声的建议。
Railway noise has become one of the most important environmental issues of concern to the community. In this paper, the field survey and analysis of the railway noise spectrum, diurnal variation, the relationship between noise and train flow, the maximum impact factors and the relationship between the noise level and the train speed, and then clarify the train noise characteristics, And put forward suggestions on how to control railway noise.
