Transit operators, transit patrons and communities have all expressed concern over rail transit noise and indicated that its reduction should have priority. The UMTA Urban Rail Noise Abatement Program has assessed the dimensions of this problem to identify, develop and test noise abatement technology, and to share such control techniques with transit systems, suppliers, manufacturers and others concerned with urban rail noise. The Program consists of three major areas: Noise Assessment in which the mechanics of noise transmission and methods of acoustic measurement are described; Technology Development and Evaluation in which the various types of wheel/rail noise are described along with damping systems, as well as the problems of elevated structures, subway tunnel vibration, ground-borne noise and propulsion system noise.
