ACOUSTIC DIFFRACTION FROM AN
ABSORBING HALF PLANE DUE TO A POINT
SOURCE IN A MOVING FLUID
BASHIR AHMAD AND LAILA NAYEL ALSHARIEF

Abstract. We discuss the diffraction of a spherical acoustic wave (emanating due to a point source) from a semi-infinite plane satisfying Myers' impedance condition on both sides of its surface in a moving fluid. The introduction of Myers' impedance condition improves the diffracted field. The method of solution consists of Fourier transform, Wiener-Hopf technique and the asymptotic methods.
