耳是人体构造最为精密、复杂的器官之一,也是人体十分重要的组成部分,但如果不会正确使用耳朵,会给耳朵带来一些伤害,严重的甚至会造成耳聋。耳朵的结构耳朵的结构分为三部分:外耳、中耳、内耳。外耳接收外界的声音,并将沿着耳道引起鼓膜震动。中耳鼓膜的震动引起三块小骨:锤骨、砧骨和镫骨震动,将声音传到内耳。内耳可产生神经冲动,冲动沿听神经转为神经能,从那声音的信息传递
Ear is one of the most sophisticated and complex organs in the human body. It is also a very important part of the human body. However, if the ear is not used properly, it will cause some damage to the ear, which may even cause deafness. Structure of the ear The structure of the ear is divided into three parts: the outer ear, middle ear, inner ear.

The vibration of the middle ear tympanic membrane causes three small bones: the malleus, the incus and the tarsal bone to vibrate, transmitting the sound to the inner ear. The inner ear can produce nerve impulses, the impulses turn into neural energy along the auditory nerve, and from the sound information
