The flow induced oscillation in a cavity exposed to external high speed flow and its suppression by means of sound excitation at the leading edge of the cavity are experimentally studied.
Through the border conditions of damping layer combined with the shell the coupled oscillation equation was solve, and radiation sound field expression was shown using the shell displacements.
