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).

To increase the speed of Shinkansen trains, it becomes more important to reduce the noise generated from Shinkansen cars. We developed the high-speed test trains "FASTECH360" that have new equipment such as low-noise pantographs, pantograph noise insulation plates and sound-absorbing panels for the noise from the lower area of car bodies. We conducted running tests using "FASTECH360" from June of 2005 to June of 2009. As a result, the noise level of "FASTECH360S"(runs only on Shinkansen line) at the speed of 360km/h is reduced by more than 4 dB compared to that of series E2-1000, present commercial trains, at the speed of 360 km/h (at a distance of 25 m from the track). We also performed the noise analysis of "FASTECH360S" at 360 km/h. Consequently, we estimated that pantograph noise contribution to the overall noise level was reduced by about 7dB compared to that of E2-1000 at 360 km/h and contribution of noise from the lower part of cars to the overall noise level was reduced by about 1dB as well.
