A new formulation is derived for obtaining the modal frequency response (MFR) of a coupled acoustic-structural system, by using an orthogonality condition of a coupled system. An improved technique is then proposed to compensate the effect of truncated modes, which are the lower and higher modes beyond the frequency domain of an MFR analysis. A coupled acoustic- box model is used to confirm the applicability of the proposed method.
