Comparison of harmonic response curves of a coupling system with elliptical panels solved using the current method and ANSYS. (a) The velocity response curves at (0.785, 0.264, 0.5) on the upper panel; (b) The velocity response curves at (0.889, 0.30, 0) on the lower panel; (c) The sound pressure response curves at (0.926, 0.414, 0.2) in the cavity.
