Myers. On the acoustic boundary condition in the presence of flow, J. Sound Vibration 71 (1980) 429] and present an improved form of the analytic solution for the diffracted field. The importance of the work lies in the fact that Myers condition (a generalization of Ingards impedance condition) is now the accepted form of the boundary condition for impedance barriers with flow and hence yields a correct form of the field. The method Of solution consists of Fourier transform, Wiener-Hopf technique and the modified method of stationary phase. (c) 2005 Elsevier Inc.
