In this report the author presents and discusses the results of an experiment in estimating the extent of annoyance caused by traffic noise on people living in the Swedish towns of Gothenburg, Stockholm and Visby. A sample of the inhabitants of the streets to be measured, were asked whether they were "very annoyed" by traffic noise and the percentage who answered yes used as a criterion. Noise measurements were performed shortly after the interviews. The traffic noise was recorded on a tape recorder and the equivalent continuous a weighted noise level (laq) was calculated using the measured noise levels and the number of vehicles per unit time, obtained from official statistics for the different streets. The results of this experiment are put forth in tabular and graphical form showing the relation between the "percentage very annoyed" and laq at each measurement place, and the relation between "the percentage very annoyed" and the number of heavy vehicles per unit time. The results of the study point to the importance of peak noise events in city traffic for the development of reactions among the exposed population. (TRRL)
