Auralisation: Influence of vegetation

The vegetation has to be a forest-like, broad and very densely grown belt of vegetation – otherwise the physical noise reduction is close to zero. These examples show the effect of a 50-metre broad belt of forest trees (10 metres high) situated 15 metres away from the roadside.
