Abstract Passengers' demands for riding comfort have been getting higher and as the high-speed railway develops. Scientific methods to analyze interior noise of train are needed operational transfer path analysis (OTPA) method provides a theoretical basis guidance control overcomes shortcomings traditional method, which has high test efficiency can be carried out during working state targeted machine. The OTPA model is established from aspects "path reference point-target point" "sound...
Track construction is likely to exert a significant effect on railway environmental noise. In this study, detailed comparative investigation was conducted analyze the differences in external noises generated by Chinese high-speed train passing through typical lines at different speeds. Acoustic experiments were both viaduct and embankment sections using microphone array having 78 channels, distinguish effects of two types track structures sound fields around these, identify sources,...
