Soundscape approaches in urban planning: implications for an intervention framework
* Presenting author
There is increasing demand for innovative approaches to decrease the negative impact of noise by sound-conscious design. While the health effects of environmental noise are well mapped, little is known about the effectivity of interventions on health. This is one of our conclusions in the WHO-review on health impacts of noise interventions. More and better interventions studies are needed, in particular for sources other than road traffic, and for health outcomes other than annoyance. Soundscape interventions were in this review classified under the category” Other physical interventions”. Three out of four studies in this domain demonstrated potential efficacy. Although soundscapes seem essential for urban planning, guidelines on how to implement this knowledge are missing. Against this background an inventory of architectural soundscape projects in the Netherlands and elsewhere was made, combining interviews with experts and planners with a literature review. This led to the conclusion that well documented approaches all combined changes in the physical environment, with stakeholder involvement. In that way a sense of ownership was created by the interventions, forming an additional category in the typology of interventions as canvassed earlier. This paper suggests some extensions the typology of interventions.
