734 車上設置型デバイスによる鉄道車輪/レール系騒音のアクティブ制御 [in Japanese] 734 Active Control of Railway Wheel/Rail Noises by On-vehicle-type Devices [in Japanese]
Access this Article
The possibility of a concept of active sound cancellation control based on the wave absorbing principle of conventional railway wheel/rail rolling and impact noises by on-vehicle-type devices was examined. First, theoretical simulations on the basis of BEM were executed, and then the experiments of active noise control were carried out by using multi-device-units installed on the panel system simulating the floor/side wall of railway cars, where both the simulated random rolling noise and impact noise measured in the real field were used. As a result, it was verified that the sound cancellation effects are actually observed over the relatively broad seeable space from the rail, showing the validity of the proposed concept.
