What can sound artists contribute to the sonic design of public urban environments? And why is it important to involve sound artists in this design process? Although slowly, it seems as if a transformation is taking place in the way (local) governments deal with the (re)design of public urban spaces: not only can we notice - at least in The Netherlands - more attention for the sonic design of those spaces; emphasis also shifts a bit from noise measurements and noise reduction to a more nuanced approach in which citizens are asked after their aural experiences and desires. This opens the prospect to not only regard sounds in public spaces as a problem but also as an opportunity: sounds can contribute in a positive sense to the experience of an environment; and it is possible to constructively influence and design a sonic environment. Enter sound artists. Not only are they experienced and (often) unbiased listeners which may help to not denounce certain sounds a priori (e.g., because of their sources); they can also offer unexpected solutions to specific problems and work with the unexplored sonic opportunities of an urban site.
