摘要
从物理学的基本原理出发，结合耳膜的特殊结构和振动模式，得出打击脉冲，并比较麦克斯-玻尔兹曼的统计理论，得出声音在人耳内部出现传递因子S（ω）；在超声区，S（ω）出现截止频率ωc，在次声区．打击脉冲不连续，出现临界频率fc（fc＝20Hz）[1]。
Based on the principle of physics, and combining with the special Structure and vibration of the ear-drum we get a impact pulse. By comparing with' Theory of Maxwell-Boltzmann', we get a transmission factor S(to).Which within ultrasonic rauge presents cutoff frequency ωo., and in the infrasonics, the impact pulse discontinues and the critical frequency fc appcars.(fc=20Hz).These results also agre with the boundations of 'Fletcher-Muuson' and 'Robinso-Dadson' equal loudness curves.
