- At present ,the prediction result of highway traffic noise is quite different from the actual situation ,the main reason of which is that the prediction model of the sound source is not perfect .This paper considers the actual height of highway sound source ,uses acoustic simulation software to build a sound source model whose vertical height is consistent with the actual situation ,analysis the prediction results of sound receiving points and discovers that: compared with the equivalent simple sound source model , that having considered the sound source height much more accord with the actual highway situation so that the prediction accuracy will be improved , which will provide reference to the road traffic noise control.
