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

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
