In order to elucidate the characteristics of rolling noise of wheel / rail system which is to be the main cause of the conventional railway noises, first the coupling vibration analyses were carried out by using an infinite length rail model with tread surface roughness and FEM model of wheel, and then based on BEM with the boundary conditions of obtained vibration responses , the acoustic radiation powers and the distribution of SPL of sound fields on both of the slab and ballast tracks were calculated for the wheels with straight , TGV-type and corrugated web. Examining the influences of wheel configurations to the rolling noise, the methods of countermeasures to reduce that noise were implied.
