NOISE IN GROUND TRANSPORTATION SYSTEMS

Passage of the Noise Control Act of 1972 has given added impetus to the drive for noise reduction. Section 17 of the Act empowers the Environmental Protection Agency to issue railroad noise standards which will be enforced by the Federal Railroad Administration (FRA). FRA's High Speed Ground Transportation R&D program has a goal of substantially increasing the speed of ground passenger travel. Without improvements in the state-of-the-art of noise suppression and noise avoidance higher speeds will inevitably mean higher noise levels. Therefore, the new systems developments are forced to include good acoustic designs by specifications of maximum permissible noise levels. Data on the wayside noise levels of various rail, transit and tracked air cushion vehicle systems are tabulated, and for comparison the noise specification used for developing the DOT ground vehicles is shown. Noise sources for guided ground transportation are discussed with respect to steel wheels, railroad yards, tunnels, elevated guideways, aerodynamics, propulsion, tracked air-cushion vehicles, tracked magnetically levitated vehicles, and tube vehicles. It is indicated where research and development can contribute to noise abatement.
