Validation of eardrum model by comparing experimental data against model results. (a) Middle ear pressure gain: the ratio of the pressure in the vestibule of the cochlea to the pressure in the ear canal. Model result (black line) is compared with two sets of experimental results. The range of results reported by Nedzelnitsky (21) are within the gray area bounded by blue lines, whereas measurements by Decory et al. (22) are shown by the green lines. The model result agrees in both magnitude and phase with the experimental measurements. (b) Displacement measurements of four points on the eardrum relative to the center of the eardrum (umbo). Solid and dashed blue lines indicate measurements from Decraemer et al. (23), whereas black lines are the model calculations. The model correctly predicts the response magnitudes at each point. An exact match of the data and calculations is not expected given that only an approximate position of the measurements is known.
