For a better sonic understanding of urban space in transformation we will produce sound maps. As soon as elements on a map exist, they have value and generate new meaning by their name. Mapping a sound environment requires an understanding of the conditions that lead to certain sounds and vibrations and their possible effects and affects. For a sonic mapping of the Brussels L28- area in transition, the PhD. Research Project will bring together different skills: the artist – cartographer – to introduce the critical potential of artistic cartography, the sociologist planner to examine the social and cultural characteristics of an urban sound environment; a field recorder- sound artist to collect and capture sounds and vibrations, the architect- designer to demonstrate sonic vibrations.
