RAILWAY NOISE - CALCULATION AND MEASUREMENT

This paper shows how a new examination of some old English data on railway noise has revealed a new way of estimating train speeds, and allowed comparison with published empirical railway noise data. In 1982, an extensive noise monitoring programme, using a data logger, was conducted adjacent to the main railway line near Wellington, Somerset, England. Two 24-hour recordings were made at 12 measurement positions in a 3 x 4 grid across the site. The data tapes were processed to give Leq (1 hr) values. This procedure was time- consuming, but provided extensive data. Using synchronised clocks, it has been found possible to use single event histories to compute train speeds. A program compares the events, then estimates the average speeds and directions of trains. It compares the event durations at two locations, to check that train speeds have remained fairly constant. The two locations were 1050m apart, about 30m from a piece of track in a 4m cutting. Time plots of measured SEL were taken, and the resulting train speed estimates were reasonably good. The paper also presents some results on local inhabitant's response to rail and road noise in the study area. For the covering abstract see IRRD 867830.
