本文给出了列车振动声的一些典型数据。结果表明，主频率范围在40 Hz和100 Hz之间，这是车轮/轨道共振的所在。定性描述了三种可能的生成机制;讨论了它们对最重要参数的依赖关系。只对地面结构声传播进行了一些评论，对建筑物振动没有任何评论。这些现象非常强烈地依赖于细节（不均匀性，特殊结构等）。很难具体说明。因此，除非有大量的经验数据，否则很难做出可靠的预测。
Abstract Some typical data are given for structure-borne sound excited by train traffic. They show that the dominant frequency range is between 40 Hz and 100 Hz, where the wheel/track resonance lies. Three possible generating mechanisms are qualitatively described; their dependence on the most important parameters is discussed. Only a few remarks are made on structure-borne sound propagation in the ground, and nothing is said about building vibrations. These phenomena depend very strongly on details (inhomogeneities, special constructions, etc.) that are extremely hard to specify. Therefore reliable predictions are very difficult unless a large amount of empirical data is available.
