Reduction of rolling noise as well as aerodynamic noise still calls for serious attention on controlling Shinkansen noise even if the speed of the train comes close to 300 km/h. This paper presents results of on-line tests with resilient wheels which were adopted tentatively in order to lessen the rail vibration, considered to be a major cause of wheel/rail noise in Japan. In the case of under-car noise and rail-side noise, the all-pass levels of resilient wheels are not lower than those of solid wheels. As a result of attenuation by transmission or diffraction in higher frequencies, in-car noise and 25m point noise can be lowered by 1-2 dB when using resilient wheels. The decreasing effect of resilient wheels on structure noise was proved to be at least 3 dB.
