Auralisation: Road Surface Age

Road Surface Age

The type, condition and age of the surface may influence the road noise significantly. The effect is normally compared to a reference surface (in Denmark surface type SMA 11). A noise reducing surface is obviously less noisy than the reference surface, but the age and condition of the surface have influence on the noise as well. The noise increases with age.

These examples show a new surface compared to a 7-year old and a 17-year old reference surface (SMA 11).
