摘要
分析了德国铁路噪声在线监测的应用背景,介绍了德国铁路噪声实时监测系统的研究现状,包括测量站点的选取原则、技术结构和具体信息,列车声压级曲线时域连续变化图、单次列车通过声压级曲线图、单次列车通过参数表和等效声压级曲线图/表等测量结果的表达方法,以及无效数据的处理方式等,为我国建立铁路噪声自动监测系统提供参考。
The application background and research status of on-line railway noise monitoring system in Germany were introduced in this paper,including site selection principle,technological structure and specific information,time domain continuous variation diagram of sound pressure level curve,sound pressure level curve of single train,the expressions of single train parameter list and equivalent acoustic pressure level curve/list,and invalid data processing.It provided a reference for the establishment of automatic railway noise monitoring system in China.
