The propagation of sound in a street has previously been treated almost exclusively by the use of ray-tracing techniques. As a result, the effects of scattering from objects and protrusions in the street have not been taken adequately into account. In this paper, the sound field is analysed in terms of its propagating modes. The use of this technique allows the effect of scattering to be calculated, assuming a rather simplified model of a scattering surface. Although a number of important assumptions are made, the predicted attenuations at points down a street are in good agreement with results obtained from model studies. These attenuation curves are also similar in form to those obtained in full-scale tests. (A) /TRRL/
