TECHNOLOGICAL DEVELOPMENT RELATING TO MEASURES AGAINST SOURCES OF NOISE

High-speed Japanese National Railways' trains produce noise at four points: pantograph sliding on the contact wire; air passing over and about the train; wheel/rail contact; and secondary noise generated by vibration of trackside structures. Increasing restriction on train noise generation is being anticipated by tests conducted on the Tohoku Shin Kansen now being built. Work has been done on existing lines on sound instrulating walls, ballast mats, details of the concrete-slab track construction and on damping of noise sources on the trains. Extensive measurements have been made on noise propagation from Shin Kansen trains.
