الملخص EN

Establishment of three-dimensional finite-element model of the whole auditory system includes external ear, middle ear, and inner ear.

The sound-solid-liquid coupling frequency response analysis of the model was carried out.

The correctness of the FE model was verified by comparing the vibration modes of tympanic membrane and stapes footplate with the experimental data.

According to calculation results of the model, we make use of the least squares method to fit out the distribution of sound pressure of external auditory canal and obtain the sound pressure function on the tympanic membrane which varies with frequency.

Using the sound pressure function, the pressure distribution on the tympanic membrane can be directly derived from the sound pressure at the external auditory canal opening.

The sound pressure function can make the boundary conditions of the middle ear structure more accurate in the mechanical research and improve the previous boundary treatment which only applied uniform pressure acting to the tympanic membrane.
