Surface Transportation Noise and Its Control

Surface transportation creates most of the noise pollution imposed on our communities today. Reduction of this noise impact requires effective preparation and enforcement of regulations to control noise sources, and methods and locations of operation. At the Federal level, such action has begun, within the limited authority available. Concurrently, research and development programs are demonstrating that means to satisfy noise control regulations are technically practical and economically reasonable. This paper provides a brief review of Federal regulatory areas and corresponding R&D activities pertinent to surface transportation noise abatement.
