Abstroct This report describes the noise climate on and neal the Greater Cleveland Regional Transit Authority (RTA) , formerly the. i i : ’A Or Cleveland Transit System (CTS), Airport Line. It is series of coordinated assessments sponsored by the furban Mass Transportation Administration and technically administered., through the Transportation Systems Center of the U.S. Dgp^tAenn 1979 of Transportation. The RTA urban rail transit line has approxi- mately 19 miles of two-way revenue track (of which about one mile is in subway), and 18 stations. RY Noise level data is given for specific measurements cars, in stations, and along the non-subway wayside at appropriate locations. Based on these measurements, in-car average maximum A-weighted sound levels, L (Max) , are estimated to be in the 80 to 84 dBA interval for 75 percent of the RTA route mileage in St. Louis cars, and for 95 percent of the route in modified Pullman cars. Sound levels in standard Pullman cars are in the 85 to 89 dBA interval for 63 percent of the RTA route. Wayside L^(Max) levels, at 15m (50 ft) from the near track, are in the 90 to 99 dBA interval for all above ground route mileage. Station L^ (Max) levels range from 77 to 88 dBA and are in the 80 to 84 dBA interval for 89 percent of RTA stations. The rationale for choice of measurement sites and the methodology for arriving at the summary noise distributions from the data are discussed explicitly. Measurement and analysis instrumentation and procedures are also described. 17. Key Words 18.

PREFACE This report has been prepared under the Urban Rail Noise Abatement Program being sponsored by the Urban Mass Transportation Administra- tion's (UMTA's) Office of Rail and Construction Technology. The Noise Abatement Program is being managed at the Transportation Systems Center for UMTA. The objectives of the Noise Abatement Program are to assess noise produced by urban rail transit opera- tions and to appraise methods and costs for reduction of such noise. This report is one in a series of six noise assessment reports covering noise due to transit operations on seven rail transit systems in five U.S. cities. Consistent results of the six assess- ments were achieved through use of standardized noise measurement and data reduction procedures developed at TSC and tested on the Massachusetts Bay Transportation Authority (MBTA) in Boston. The assessment report for the MBTA was published in 1974 (Reference 1) Physical differences among the transit systems, as well as differences in the technical orientations of the teams, and in funds available to the teams for measurement and analysis, led to some differences in report organization, technical depth and writing style. Therefore, to provide at least introductory con- sistency among the reports for the reader, the front material, including the introduction of each assessment report, has been edited at TSC. The organization and technical content of each report, however, are basically as originally written by the res- pective teams and are, together with the accuracy of the measure- ments, the responsibility of the authors. This report has been prepared by the Boeing Vertol Company under contract DOT-TSC-850. Authors of the report were R. H. Spencer and E. G. Hinterkeuser . Technical Monitors for the program were Dr. E. G. Apgar and Dr. Robert Lotz. Liaison with the Cleveland Transit System was provided by Mr. Elmer Malcomb. Dr. Leonard Kurzweil of the Transportation Systems Center directed the final technical editing of the report. Ill 1.
