Here's what it looks like to see a close-up of human hair cell stereocilia inside the ear. These detect mechanical movement in response to sound vibrations.
这张图片看起来好像是在耳朵里面对耳毛细胞进行近距离观察时拍摄的。耳毛细胞的主要功能是发现对声震作出反应时产生的机械运动。
Loud sounds can stress and potentially damage delicate hair cells in the inner ear that convert mechanical vibrations, or sound, to electrical signals that the brain interprets as sound.
高音调的噪音可以压迫和潜在损伤内耳微毛细胞，噪音转化为机械振动，或声音，或电信号，在大脑再转化为声音。
The middle ear converts sound waves that vibrate the eardrum into mechanical vibrations for the cochlea, the hearing part of the inner ear.
外耳包括耳垂和外耳道——用于把声波引入鼓膜，使之振动鼓膜。中耳将振动鼓膜的声波转化成对耳蜗——内耳的接听结构——的机械振动。
