A STUDY OF THE MAGNITUDE OF TRANSPORTATION NOISE GENERATION AND POTENTIAL ABATEMENT-TRAIN SYSTEM NOISE

The noise from an individual vehicle is a function of the physical characteristics of the vehicle, the way in which the vehicles is operated and the construction characteristics of the vehicle's guideway, e.g., rail condition, roadbed supporting structure. Noise reduction at the source can be obtained by altering the vehicle and/or the guideway and by changing the way the vehicle is operated. Analysis of contemporary mass transit vehicle noise indicates that the rank order of conventional rail vehicle noise sources is: (1) wheel and rail system, (2) propulsion system and (3) auxiliary equipment. Noise levels alongside the right-of-way, are a function of the vehicle type, its operation and the configuration of the roadbed and surrounding areas. For a given vehicle and guideway, the right-of-way configuration has the greatest impact on the sound levels received at a specific wayside location. Rail vehicle wayside noise levels can be reduced by interrupting the sound transmission paths between the vehicle and the receiver. To the extent that this is achieved, rail vehicle wayside noise levels can be reduced in a manner which is similar to that used for highway noise reduction.
