Abstract
The CartASUR project focuses on urban dwellers' feelings and aims to link perceptual data (from surveys) with physical urban data (geographic and urban databases) in order to design a prediction model for a new indicator of soundscape quality: sound pleasantness. Perceptual survey data makes it possible to understand how each noise source (cars, voices, birds…) influences the overall opinion of sound pleasantness. The first step consists in classifying perceptual data according to noise source which influences the urban dwellers' overall opinion. This paper proposes geographical reading of this classification based on the notion of urban context and shows two methods of spatial analysis to predict urban context in whatever point in the city. Different tools such as an acoustic horizon and map density are presented and used.
