IMPROVING THE PERFORMANCE OF TRAFFIC NOISE BARRIERS

This paper describes research carried out at TRL to improve the acoustic performance by deepening the acoustic shadow cast by the noise barrier. To aid optimisation a mathematical modelling technique using the Boundary Element Method (BEM) has been used to predict the noise reducing properties of a wide range of barriers. Some of the most promising designs have been tested at full scale which has involved the construction of a unique noise barrier test facility (NBTF) at TRL. It was concluded that the average noise screening of simple barriers can be increased significantly by relatively simple modifications. (A)
