Prediction of traffic noise from expressways-Part I: Buildings flanking one side of expressways

Abstract

Prediction models have been derived using a semi-empirical approach for traffic noise propagation in open space as well as the facade effect from buildings flanking one side of the expressways. The models are able to predict the L10 to within 2 dB(A). The phenomenon of experiencing higher L10 as one goes up in the building is easily explained by the ground effect. The models are useful for the planning of land use in order to achieve desirable noise levels in residential buildings. © 1989.
