摘要
从物理学的基本原理出发 ,结合鼓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 =2 0Hz) .这些结论与弗莱彻·蒙森 (Fletcher -Muuson)和鲁宾森·达德森 (Robinson -Dadson)
Based on the principle of physics, combining with the special structure and vibration of ear-drum, we get impact pulse. Comparing with ' Theory of Maxwell-Boltzmann', we get a transmission factor S(ω). This factor within ultrasonic appears cut off frequency ω c, and in the infrasonics, the impact pulse is noncontinuous and the critical frequency fc appears.(fc=20?Hz).These results also agreed with the boundary of 'Fletcher-Muuson' and 'Robinson-Dadson' equal loudness curves.
