Variation of rolling noise during train pass-bys
conference paper
Railway pass-by noise measurements on different types of tracks sometimes display a significant difference between the rise and decrease in rolling noise at the front and the back of the train. This can potentially have different causes. Whilst this may not necessarily be relevant for the total passby noise level, it seems to indicate that the characteristics of the railpads or fastening system vary during the pass-by. This effect has been observed on different tracks and is clearly visible in a spectrogram taken over sufficiently long measurement time. Some examples of this phenomenon are presented and discussed in this paper.
