Wheel/rail Noise above 10 kHz Generated on a Curved Sections

It is well-known that wheel/rail noise from 250 Hz to 4 kHz has a greater influence on wayside noise along railway lines. However, when a train runs on a gently curved section, noise due to wheel and rail vibrations above 10 kHz could have a greater contribution to the total wayside noise. This paper therefore investigated the contribution of the high-frequency noise to wayside noise on a high-speed railway line through field tests and static experiments. It was found that wheel noise above 10 kHz is generated mainly by the leading wheel on the outside rail of each bogie, and that the noise level depends on train speed.
