Physical and perceptual characterization of road traffic noises in urban areas for a better noise annoyance assessment
Résumé
The work presented in this paper intends to contribute to improve noise maps by a more meaningful characterization of urban road traffic noises. In this aim, in situ recorded pass-by noises, following an a priori physical typology, are submitted to a panel of subjects via a free categorization and free verbalization tasks. This resulted in the proposal of a perceptual and cognitive typology of road traffic pass-by noises that was further confirmed by the results of a pair-wise comparison test. The 7 categories of the perceptual and cognitive typology were then studied separately from noise annoyance point of view. Annoyance indicators were then proposed to characterize each category of vehicle pass-by noises by taking into account their spectral and temporal specificities.
