Coupled analytical and empirical structural-acoustic models of an aircraft fuselage and wing structure driven by propeller wake/vortex induced loading are developed to predict structure-borne noise transmission into the aircraft cabin. Free-interface component coupling functions are used to couple the system components for structure-borne noise prediction. Predicted interior noise levels for the first two propeller tones are compared to laboratory-based test results to verify the predictive procedures.
