EFFECTIVENESS OF NOVEL SHAPED BUNDS IN REDUCING TRAFFIC NOISE

Earth bunds are the most widely used method of noise control in the UK and many other countries due to their low cost, low maintenance, relatively pleasing appearance and the support of a wide range of flora and fauna. Little effort has been made into designing more efficient shapes, which can improve on the noise screening of standard designs of bund. The use of recent developments in boundary element methods (BEM) and the advent of relatively cheap, high speed computing have enabled predictions to be made of the screening performance of large and complex shaped bunds. The paper reports on the results of modelling a range of modified bunds in order to identify acoustically efficient yet practical designs. (A) For the covering abstract see IRRD E101083.
