An asymptotic solution of the scalar wave field due to a point source above a locally reacting plane surface is obtained by a modified saddle point method. Numerical calculation indicates that the relatively simple solution is more accurate than the Thomasson asymptotic solution and the Chien-Soroka

In this paper, the Dual Boundary Element Method is formulated and applied to study outdoor sound propagation where acoustic barriers are modelled as non-thickness bodies that may have different impedance conditions at each side. Standard and hypersingular integral equations are applied on each side
