Abstract:

This report summarizes seven individual noise assessments of the urban rail transit systems in Boston, New York City, Philadelphia, Lindenwold (N.J.), Cleveland, Chicago, and San Francisco. The assessments were performed by DOT and contractor research teams using a noise measurement methodology developed at TSC and tested on the MBTA in Boston. Sound level measurements were taken inside the transit car, in stations, and in the community situated near the rail rights-of-way. For the purpose of this national assessment report, measured noise level data have been extrapolated to characterize sound levels at all places on each of the systems. Distributions of noise levels for each transit system are compiled in terms of the acoustic measures L(A)(Max), L(eq), and L(dn). In addition, noise levels in the wayside community (including trains) are compared with estimated ambient community noise levels which would exist if train noise were not present. Finally, estimates are made of the number of persons exposed to the various levels of noise in the transit car, station, and wayside community. Distributions of noise levels and noise exposure are presented for a composite rail system, made up of all seven transit systems. Several Government and industry noise level guidelines applicable to rail transit systems are discussed. Sound level distributions for each of the seven systems are compared with noise level goals developed by the American Public Transit Association.
