In this paper, To estimate the train exterior noise and environment noise which are occur when High-Speed EMU is driving with the speed of 370㎞/h, Estimated sound source about noise that is appeared during operation based upon noise SPL values. Based on aero-dynamic noise source and wheel-rail noise source, these were already used to the existed research, we have estimated each sound power about measured noise, and computed the sound source to apply on the High-Speed EMU, and also calculated the sound power in case of the maximum operation speed of 370㎞/h.
