Urban areas experience a continuous increase of population and mobility going along with increased noise exposure of the residents and a decline of green spaces. The objective of this project is to assess the effects of green spaces as facilitators and noise as impediment to recover from stress in Switzerland. The project will combine laboratory acoustic and visual experiments, field experiments, remote sensing assessments and a Swiss-wide PPGIS survey. This interdisciplinary approach will result from the cooperation of the Swiss Federal Laboratory for Materials Science and Technology (EMPA) and the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL). The results will have an impact on the Swiss noise legislation and the implementation of the spatial planning act.
