LABORATORY STUDY OF THE INFLUENCE OF NOISE LEVEL AND VEHICLE NUMBER ON ANNOYANCE

A laboratory study has been carried out to examine the relationships between annoyance and the level of road noise made up of background noise with emergent noisy truck passages. The annoyance caused to test persons was examined in experimental situations for periods of 30 minutes. There were two independent variables: the number of truck passages varied from three to 30, and the categories of overall noise level (leq for road noise) were 50, 55 and 60 db(a). Generally, the results showed that for a constant leq level, annoyance increases with the number of truck passages as far as a certain threshold, where it tends to stabilize; for a constant number of truck passages, the annoyance increases with the leq level. It is found that although the index leq is a better criterion of annoyance than the number of truck passages a composite index nevertheless appears to be reliable in predictions. (Author/TRRL)
