摘要:: 本研究旨在论证人耳传声系统的简明振动学原理。借助理论性研究方法对外耳、中耳和内耳的传声功能逐一进行论证，详细阐明外耳的共振作用，揭示中耳锤-砧骨刚体的传声原理。首次通俗阐明内耳基底膜的分频作用和基底膜上行波的成因，提出听觉的共振敏感性和阈值敏感性概念。本研究将声振动基础知识与研究获得的新知识相结合，构建了简明和系统的人耳传声的振动学原理。

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.
