DEVELOPMENT OF AN ACOUSTIC RATING SCALE FOR ASSESSING ANNOYANCE CAUSED BY WHEEL/RAIL NOISE IN URBAN MASS TRANSIT
A number of recent studies of the impact of train noise on the community are reviewed. From this information and the results of other noise-annoyance studies, a scale for rating the annoyance of urban transit system operators and patrons, as well as the surrounding community, caused by wheel/rail noise is recommended. In general, the peak A-weighted sound-pressure level for the given exposure should be used, with an additional 5 dB if there are pure tones present (squeal). If in comparing the different kinds of train noise (squeal, impact, wheel roar, etc.) the total exposure is to be assessed, an additional term, 10 log T, should be added to the mean peak noise (where T is the total exposure in seconds during any 24-hour period).
