LABORATORY STUDIES ON TRAFFIC NOISE ANNOYANCE

A laboratory study was undertaken to investigate the relation between traffic noise and annoyance with special reference to the number of noisy events. Students were exposed to different noise conditions for 45 and 120 minutes whereafter their reactions were assessed using a questionnaire. The extent of annoyance was found to increase with augmenting leq levels but only when the number of noisy events remained equal. At equal leq levels an increased extent of annoyance was found when the number of noisy events increased from 1 to 15 per hour. The results point to certain limitations in the validity of the equal energy concept and to the usefulness of laboratory studies to investigate reactions to environmental noise. /TRRL/
