An easy-to-apply computational procedure for the study of the acoustic performance of pairs of diffusively reflecting roadside barriers is described in detail, and an experimental verification of its predictions, carried out on a 110 scale model, is presented and discussed. It is shown that, in comparison with pairs of more traditional specularly reflecting noise barriers, significant attenuation benefits are obtained not only in the shadow zone behind the barriers, but also in the unprotected zone immediately above the barriers, which proves that diffusive traffic faces of the barriers may effectively help in counteracting multiple reflection effects.
