STATEMENT OF KENNETH KNIGHT BEFORE THE PUBLIC HEARINGS ON NOISE ABATEMENT AND CONTROL

Noise ranks as the most important problem facing the steel wheel-steel rail transit system industry. Acoustic problems of vehicles in stations, in tunnels, or from aerial structures are intensified by dense urban environmental operation. At the present time the public can control or alter route locations, demand aerial structures, demand at-grade facilities be put underground or other major changes, although such design changes are often prohibitively expensive. The industry itself has been aware of the noise problems and made significant technological improvements since the first subways were introduced in Boston, New York and Philadelphia. Basic research is required to clearly establish the effects of noise upon people and to establish appropriate criteria for the noises of the type generated by transit system operations.
