VALIDATION AND REFINEMENT OF MIDDLE EAR FE MODEL USING STATISTICAL CALIBRATION APPROACH
A finite element model of human middle ear for sound transfer function from tympanic membrane to oval window has been developed and refined using a statistical calibration approach.The middle ear FE model consists of three ossicles (malleus, incus and stapes), tympanic membrane, tendons and ligaments.The uncertainty of boundary conditions and material properties of the middle ear FE model have been considered.First, the statistical information on the boundary conditions and material properties were assumed from published data.Next, the variation of umbo displacement transfer function due to the uncertainty of the material properties and boundary conditions were estimated using the eigenvector dimension reduction method and compared with those of experiments.In addition, the material properties were refined by a statistical calibration approach.Applying the identified material properties and boundary conditions, the finite element model for human middle ear has become to well represent the variations of the transfer function.
