| Summary: | A ray-based method is presented for evaluating multiple acoustic diffraction by separate rigid and
parallel wide barriers, where two or more neighboring ones are of equal height. Based on the
geometrical theory of diffraction and extended from the exact boundary solution for a rigid wedge,
the proposed method is able to determine the multiple diffraction along arbitrary directions or at
arbitrary receiver locations around the diffracting edges, including the positions along the shadow
or reflection boundaries or very close to the edges. Comparisons between the results of the
numerical simulations and the boundary element method show validity of the proposed method. |
