QUANTITATIVE STUDIES OF TRAFFIC NOISE ANNOYANCE
A continuing research program on traffic noise annoyance, involving laboratory, field, and computer modeling studies, is designed to quantify traffic sound elements which are subjectively most important to people, to determine annoying levels of traffic noise, and to analyze potential traffic noise abatement schemes. Laboratory studies of perception and preference for traffic sounds indicated that the psychologically most important elements of normal traffic noise are best measured by Leq (energy equivalent sound). Field studies showed that an Leq where 60 dB. is exceeded 24% of the time is the traffic noise level at which people become willing to pay for noise reduction. A community noise model has been developed for estimating the effectiveness of possible traffic noise abatement schemes in terms of the change in the number of people potentially exposed to various traffic noise Leq levels.
