Annoyance due to combined road traffic and industrial noises: a simulated environment experiment

摘要

Total annoyance due to combined noises is still difficult to predict adequately. Actually, no total annoyance model leads to a consensus among the scientific community. In this context, the paper describes a simulated environment experiment where subjects perform activities in a simulated living room while exposed to noise sequences combining road traffic and continuous industrial noises. The effects of acoustical factors (exposure to road traffic noise, and exposure to industrial noise) on annoyance are firstly investigated. Then psychophysical and perceptual models of total annoyance are tested in order to (1) compare them using the data collected during the simulated environment experiment, and (2) confront them to data collected in situ. The results of this study confirm that perceptual models are able to predict annoyance better than psychophysical models.
