Auralisation: Influence of vegetation on road noise
How much influence does vegetation have on traffic noise, and what does it take to make it work as noise reduction?
Sometimes, vegetation along the roadside may work as noise reduction. The vegetation must 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.
