Abstract : The related problems of the radiation of sound from a line source near an infinite nonridgid strip in an infinite rigid plane baffle and of the scattering of a plane wave by the same strip are solved when the boundary condition on the strip is: pressure = (velocity normal to the strip)(onstant acoustic impedance of the strip). Some numerical results are presented for a strip which is very wide as compared to a wavelength. (Author)
