A new urban park is proposed in the centre of Stockton-on-Tees, England. One of the design’s features is the incorporation of a road, which will be converted from dual to single carriageway. How will the road traffic noise affect the soundscape for the users of the various parks spaces? A combination of traditional methods such as noise propagation modelling and newly developed soundscape assessment and analysis tools were used to answer this question. This approach was able to identify the biggest acoustic risks for the current design, and propose potential improvements for the sonic environment. The challenges encountered with this novel practical application of the soundscape method in a commercial context are discussed.
