MODEL FORMULATION OF TRAFFIC NOISE AT EXPRESS HIGHWAY

The traffic noise produced by motor vehicles, as main sources in urban areas, is part of general environment problem which inflicts a serious damage to the health of human beings and lowers the labour productivity. In order to control acoustical sound level in urban areas, methods for prediction of the traffic noise are necessary, In this paper, we present the various predictive models, Griffith and Langdon noise model, Burgess traffic noise model, Centre Scientifique et Technique du Batiment (C.S.T.B.).
