Sound Wave Diffraction by a Cavity with Partial Lining

Abstract

Diffraction of sound wave through a cavity with partial lining is analyzed rigorously. Fourier transform technique and Mode Matching method are used to obtain Wiener-Hopf(WH) equation and solution. The solution of the problem is found for various problem parameters numerically. The effect of the different parameters such as the lining length, cavity depth, etc. on the diffraction are illustrated graphically. The results are compared numerically with an existing study and found to be consistent.
