In this study, a three-dimensional finite-element (FE) model of the human ear was established, including the ear canal, middle ear, loading of the cochlea. The acoustic-structure interaction analysis was performed using this coupling model. The impulse-responses of the pressure in the ear canal and the displacement of the stapes were calculated step by step, and the time domain responses were transformed into frequency domain responses by FFT. The general tendency in the frequency response of the each results obtained using the FE model was nearly same as the measurement results. In this way, the measurement of "Otorefrectance" which is a new hearing test was simulated by the analysis using the FE model.
