Abstract: The ear is the important organ for hearing with a typical structure for transmiting vibrations from the sound exicitation and change them into the impulses of the acoustic fibers. The establishment of a complete and effective biomechanical model of the human ear and the study of its biodynamics behavior may help us understand and analyze the sound transmission mechanism. The study of the change in the sound transmission mechanism at a pathological state and after a surgery may provide a theoretical basis for studying the mechanical mechanism of relevant clinical diseases. The present paper reviews the progress of biomechanical models of the human ear as a hearing system and their clinical applications and prospects in the future.
