STUDY OF RAILROAD NOISE REDUCTION BY NOISE-PROOF WHEELS

In recent years, noise pollution created by railroad vehicles has become a major problem that must be solved urgently. The Teito Rapid Transit Authority and Sumitomo Metal Industries Ltd. have received a subsidy from the Transportation Ministry of Japan to investigate the vibration and noise characteristics of several types of soundproof wheels. This paper presents the results of laboratory and field tests on the soundproof wheels, comparing them with conventional steel wheels. It is concluded that the resilient soundproof wheel can reduce noise under the car-body floor from 3 to 5 decibels, while the damping soundproof wheel can reduce it from 1 to 3 decibels.
