Abstract:: Abstract: The research aims to demonstrate the vibration mechanism of the sound transmission of human ear. Theoretical research methods are applied to demonstrate the functions of sound transmission of outer, middle, and inner ear. Herein the resonance process in the outer ear is elaborated. The mechanism of the sound transmission of the malleus-incus complex in the middle ear is illuminated initiatively. The frequency division function of basement membrane in the inner ear and the cause of travelling wave on the basement membrane are comprehensively demonstrated for the first time. The concepts of resonance sensibility and threshold sensibility are proposed. The essential basic knowledge of sound and vibration is combined with the new knowledge acquired from the researches to provide a comprehensible, concise, and systematic elaboration of the vibration mechanism of the sound transmission of human ear.
