Abstract
In order to reduce the wayside noise caused by passing high speed train, we have to clarify the noise sources and their characteristics and also grasp the contribution of each noise source to the overall sound level. We have been attempted to identify the noise sources by using counter maps of sound intensity level and grasp the contribution of noise sources from a noise profile of a passing Shinkansen train. Based on those data, we have developed a prediction model of Shinkansen noise. The prediction model calculates noise profiles during passage of Shinkansen train at a receiver point. The predicted noise profile agreed well with a measurement one for varied conditions.
