Naturalité urbaine : l’impact du végétal sur la perception sonore dans les espaces publics

From the point of view of the requalification of the contemporary city, the sensitive can be considered as an operator of new urban forms and questions as such the various modes of intervention on the city. It is thus a question of focusing on a logic of action on the city by the sensitive. The fine knowledge of a space passes by its sonic ambiances, revealing individual and collective practices. These ambiances, of the public place define the urbanity. Spatial forms and social forms meet there. It is moreover the interest of this research: the methods developed in favor of the sound perception in public space question dimensions of the space (sound, light, visibility, objects seized at the sensory and physical level), of the environment (interactions, exchange, social) and of the landscape (aesthetic forms). The article attempts to demonstrate the importance of the place of nature in urban environment and, more particularly, the place of the vegetation, as factor determining in the spatial evaluation but also the sound perception of the place through three squares in Grenoble. Therefore, the transformation of the knowledge and of the sound perception of the experimental sites appears with the appearance of new practices and new social representations
