Les représentations visuelles des phénomènes sonores : application à l'urbanisme

Abstract : Represent space is a continual concern for town-planners. These visualizations {maps, diagrams, plans, sections, elevations, snaps, simulation pictures) are both graphic analysis tools, designing and communicating ones ensuring the necessary coordination between the city-planners. In the same way, the difficulty for knowledge integration about sonic phenomenons in the context of development projects, is coupled with a real deficiency in graphic means at disposal to visualize sonic in a built environment. Based on a pluridisciplinary corpus of views (phonetics, acoustic, music, electroacoustic, sound ecology, plastic arts, photography), the making of this general assessment constitutes the essential part of this exploration work : analyze frames, inspired by the methodology of visual semiotics, synthesizing the picture corpus in a reasoned catalogue, classifying pictures. Four great types of visual plans [map-making, temporal transcription, diagram and perspective) are defined like medium background of representable sonic phenomenons, according to three approaches (fluxus, sonific thing, auditum). Their communicating functions (describing sonic qualities, showing sonic facts, explaining sonic concepts), are bound to their schematization degrees, of witch we have noticed four levels : indexial picture (snap type), technical drawing, sketch, outline. Realize in an experimental way on an urban sonic journey, the validity test of temporal transcription on sonagraphic background [Software Acousmographe, for musical expression) seems to confirm the significance of the borrowing of visualization tools and knowledge translations between subjects. However, adaptations are necessary so as to apply analysis to the different scales of listening : sonic object, sonic illustration, soundscape. In the long run, the integration of these visualizations in an Information Geographic System reaches a double requirement: transdisciplinary analysis of sound environment, complementary nature of audible and visible representations. Graphic and plastic inventions to come should improve theoritical overhangs, should they be sensorial, structural or conceptual.
