A literature survey on how road traffic noise is spread through vegetation has been carried out. The variations in the measured noise levels given in the different papers are considerable. The mean value of the noise reducing effect of trees and bushes is 3-6 dba/50 M. For hedges and smaller vegetation the noise reducing effect is insignificant.
