Sound diffraction around screens and wedges for arbitrary point source locations

A development is presented for the Green’s function for a point source in the vicinity of a rigid wedge. The diffraction contributions to the Green’s function for arbitrary source and listener location is expressed in a form which can be readily evaluated using the Laguerre technique for numerical integration. The present approach offers the advantages of efficient numerical evaluation and of relatively straightforward reduction to well‐known analytical approximations in limiting cases. Comparisons with previously obtained experimental and numerical results obtained by Ambaud and Bergassoli [Acustica 27, 291–298 (1972)] are presented. The comparison with the experimental results is excellent; the advantages of the present numerical technique, vis a vis that of Ambaud and Bergassoli, are pointed out.
