Abstract
The diffraction of an acoustic wave, by a slit in an infinite absorbing plane in the presence of still air and moving fluid, is investigated. The problem is solved using integral transforms, the Wiener-Hopf technique and asymptotic methods. It is found that the diffracted field is the sum of fields produced by two edges of the planes formed by the slit and an interaction field.
