A solution for the problem of diffraction of a cylindrical sound wave near an absorbing strip introducing the Kutta-Joukowski condition is obtained. The two faces of the strip have impedance boundary conditions. The problem which is solved is a mathematical model for a noise barrier whose surface is treated with acoustically absorbing materials. It is found that the field produced by the Kutta-Joukowski condition will be substantially in excess of that in its absence when the source is near the edge.
