NOISE ASSESSMENT OF THE CHICAGO TRANSIT AUTHORITY RAIL RAPID TRANSIT SYSTEM

The report describes the noise on and near the Chicago Transit Authority (CTA) urban rail transit lines. The CTA urban rail lines consist of approximately 86 miles of two-way revenue track (of which 9.6 miles are in subway) and 155 stations. Noise data are given for specific measurements made in cars, in stations, and along the non-subway wayside at selected locations. The rationale for choice of measurement sites and the methodology for arriving at the summary noise distributions from the data is discussed explicitly. Measurement and analysis instrumentation and procedures are also described.
