Modélisation de l'exposition au bruit en milieu urbain et études épidémiologiques : quelles sources sonores ? (original) (raw)

Epidemiological studies on noise in urban areas are mostly based on a modelling approach which only focuses on noise sources related to transportation and industries. Additional sources are likely to influence the ambient noise level, but the spatio-temporal influence they could have is rarely studied. The objective of this study is to identify urban noise sources that could improve environmental noise prediction and to quantify their respective contributions. An acoustic measurement campaign was conducted in frontage of 44 dwellings located on the city of Besancon (France). Measurements were compared to noise levels predictions produced from different noise maps in which sources were progressively introduced. Among the additional noise sources identified, four sources were selected and implemented in the prediction model: walkways, fountains pools, schoolyards and bus stops. The contribution of each source was analysed taking into account temporal aspects (diurnal period) and spati...
