He lost the function of his auditory nerve.

他的听觉神经丧失了功能。

Then there's the auditory nerve. You can probably guess what that's for.

然后是听觉神经。你可能会猜到那是干什么用的。

That's where the auditory nerve fibers that encode information about sound connect to the brain stem.

这里是编码声音信息的听觉神经纤维与脑干连接的地方。

You might notice that, up until the auditory nerve, the cranial nerves mostly control organs in the front of the cranium — mainly the eyes and facial muscles.

你可能会注意到，直到听觉神经为止，脑神经主要控制头盖骨前部的器官——主要是眼睛和面部肌肉。

Lastly, as the signals pass through the auditory nerve, they reach various areas of the brain like the auditory cortex, and voila, you can hear!

最后，当信号通过听觉神经时， 它们到达大脑的各个区域，如听觉皮层， 瞧，你可以听到了！

This movement triggers a signal that travels through the hair cell, into the auditory nerve, then onward to the brain, which interprets it as a specific sound.

这种运动会触发一个信号，该信号通过毛细胞传播到听觉神经，然后传递到大脑，大脑将其解释为特定的声音。

See, this is essentially your body's microphone, converting sound pressure waves into electrical impulses that are eventually sent to the auditory nerve and then to the brain.

看，这本质上是你身体的麦克风， 将声压波转换成电脉冲，最终发送到听觉神经， 然后发送到大脑。
