在人耳中,耳鼓所接收的声音经过了3块骨头传到耳蜗,耳蜗内部有一排排毛细胞,毛细胞上部是一簇簇细丝,称做静纤毛。声音振动使耳蜗中的液体活动,进而使这些静纤毛像风吹柳丝一样飘荡起来。静纤毛每次晃动,都触发被大脑理解为声音的电脉冲。当大脑接收到这些电脉冲,就会知道是什么样的 In the human ear, the sound received by the eardrums is transmitted to the cochlea through three bones. There is a row of hair cells inside the cochlea. The upper part of the hair cells is a cluster of filaments called static cilia. The vibration of the sound makes the liquid in the cochlea move, so that these static cilia float like a wind and a willow. Every time the static cilia shakes, it triggers an electrical pulse that the brain understands as sound. When the brain receives these electrical pulses, it will know what kind of
