Özet

Diffraction of sound waves from a rigid circular cylindrical cavity with an acoustically absorbing internal surface is investigated rigorously by a modified version of the Wiener-Hopf technique. The solution involves a set of infinitely many expansion coefficients satisfying an infinite system of linear algebraic equations. The numerical solution of this system is obtained for different parameters of the problem such as the cavity radius, cavity depth, cavity internal surface impedance, and their effects on the diffraction phenomenon are shown graphically.
