La topographie du paysage sonore - Un outil descriptif et prédictif des ambiances sonores

International audienceThe soundscape representation seems to encircle a real challenge as on the one hand, noise maps enable a very limited reading and management of the urban sound environment quality, and on the other hand, its reduction to the graphic element endangers the soundscape illustration: after all, the meaning of the signal represented. Yet mapping while representing a ratio/rapport to and from reality is a necessity, due to its main feature - or its vocation - allowing a quick reading of an existing or potential sound situation. In fact, the ultimate challenge is to grant significance to the represented signal as close as it is perceived in situ. The present paper describes a new methodology developed at CAPS-IST, during the descriptive phase and, thanks to computer graphics tools, in the predictive phase
