The internal ear has tiny hair cells that help sweep the sound waves ahead.

耳内有微小的毛细胞，可帮助将声波扫前方。

This can revive the dead hair cells and bring back your ear health.

这样可亡的毛细胞复活，耳朵恢复健康。

The nerve that carries the sound from the hair cell to the brain.

神经会将声音经由绒毛细胞传输到大脑。

Each of these hair cells is attached to axons in the nervous system.

每一个毛细胞都附着在神经系统的轴突上。

Let's look at a healthy liver cell, a healthy hair cell, and a cancerous cell.

让分别看看一个健康的细胞，一个健康的毛发细胞，和一个癌变细胞。

It all has to do with these tiny hair cells in our ears.

这一切都与耳朵里的这些微小的毛细胞有关。

And the way this is done is that there are so called hair cells...

转化通过所谓的毛细胞来实现。

We have specialized hair cells, and they send signals to our vestibular cochlear nerve.

有特殊的毛细胞，它的前庭耳蜗神经发送信号。

I told you already about the great things that the hair cell can do.

已经为各位介绍了毛细胞有多厉害。

The healthy hair cell divides frequently.

健康的毛发细胞分裂频繁。

So when your hair cells are healthy, they stand up kind of like a field of wheat.

所，当你的毛细胞健康时，它就像一片麦田一样竖立着。

So you can damage the sensory hair cells in the inner ear or you can damage the nerves.

所你会破坏内耳的感知绒毛细胞，你也可能会破坏神经。

Loud sounds can damage these hair cells in a way that can cause temporary, even permanent hearing loss.

巨大的声音会损坏这些毛细胞，从而导致暂时性，甚至是永久性听力损失。

So noise canceling actually does remove the sound, leaving our ears hair cells, largely unaffected.

所降噪实际上确实去除了声音，基本上不影响的耳毛细胞。

This set-up also uses a combination of fluid and sensory hair cells.

这种设置也用了液体和感觉毛细胞的组合。

This is exactly what hair cells do.

毛细胞的作用正是这样。

As we age, hearing loss can be due to death of the hair cells, what we call sensorineural hearing loss.

随着年龄的增长，听力损失可能是由于毛细胞的亡，称之为感音神经性听力损失。

This organ is riddled with so-called hair cells, each of which has a tiny hair-like structure sticking out of it.

这个器官充满了所谓的毛细胞，每个毛细胞都有一个微小的毛发状结构伸出来。

Each hair cell amplifies and reports one specific frequency and ignores all the others.

每个毛细胞会放大并汇报某个特定频率，而忽略所有其他频率。

And, as this diagram shows, successive musical tones are represented a few tens of hair cells apart along the cochlear surface.

另外，如图所示，连续的音调在耳蜗表面的表达位置相隔几十个毛细胞。
