To analyze the effects of viscoelastic properties of middle ear soft tissues on the dynamic characteristics of human ear system,a finite element( FE) model of the human ear consisting of the external ear canal,middle ear and cochlea was developed. The geometric configuration of the external ear canal and middle ear was constructed via micro-CT scanning and reverse engineering technology,and the cochlea was simplified as an uncoiled,two-chambered and fluidfilled duct. The viscoelastic material effect was introduced into the behaviors of middle ear soft tissues to represent the energy dissipation in dynamic analysis. A multiphysics coupled analysis was conducted on the model in which the coupling effects among the air in the ear canal,the fluid in the cochlea and the middle ear structures were concerned. Then a sound pressure of 90 d B SPL was applied on the ear canal to simulate the sound stimulus on normal human ear. Middle ear structural responses such as movements of the tympanic membrane and stapes footplate in response to the sound stimulus were derived by this model. Meanwhile,based on calculating the pressure of the fluid in the cochlea,the sound pressure gain across the middle ear,the cochlear input impedance and the reverse pressure transfer function of cochlea were also obtained. The results show that taking into account the viscoelastic properties of middle ear soft tissues can improve the dynamic responses of the human ear system as compared with the results of a linear elastic model,especially at the high-frequency range. The better agreements between the model results and the experimental data in the literature illustrate the necessity of considering viscoelasticity for dynamic modeling of human ear.
