Assessment of Urban Soundscapes

Abstract

This article presents the different tools for assessing soundscapes within urban public spaces and develops in particular the use of the sonic mind map. We will successively define the notions of sonic perception and representation, and sonic and spatial evaluation; we will approach the concept of soundscape and finally give details about the sonic mind-map tool. Through this tool, the soundscape of urban public spaces can be understood, not through speech analysis, but through spatial representations of memorised sonic ambiances. Investigation results based among other things on sonic mind-map analyses explain the significance of sonic spatialisation and of the sound source distance in urban soundscape assessment. Using the sonic mind map to analyse the sonic representations associated with certain urban spaces seems to be relevant for researchers in space sciences or even for urban planners.
