The effect of aeroacoustic noise on the sound level of Shinkansen train becomes more important as the maximum speed increases. In order to simulate the effect of the ground which moves relative to the vehicle, a pair of mirror image models are tested at the Maibara Wind Tunnel, which has an excellent low background noise level. Sound levels generated by several combinations of front shapes and bogie conditions are measured with a sound concentrating microphone with a paraboloidal reflector. Measurements of flow properties show that the noise is mainly generated by the vortices that are separated at the leading edge of the bogie section, travel leeward at the convective flow speed, and then impinge upon the trailing edge of the section.
