It becomes more important to reduce the noise generated from Shinkansen train for further speed-up of Shinkansen. We developed the high-speed test train "FASTECH360" that has new equipment such as low-noise pantographs, "multi-segment slider", pantograph noise insulation plates and sound-absorbing panels for the noise from the lower area of car bodies. We investigated the noise distribution of "FASTECH360" by using a spiral microphone array, and we have taken countermeasures for the noise sources of "FASTECH360" based on the primary results of high-speed tests. Currently, the results show that the noise level of "FASTECH360" at the speed of 330km/h is approximately equal to that of the present commercial train at the speed of 275km/h (at a distance of 25m from the track).
