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

耳内有微的细胞，可以帮助将声波扫向前方。

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

这样可以使死亡的细胞复活，使耳朵恢复健康。

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

神经会将声音经由绒细胞传输到大脑。

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

每一个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.

让我们分别看看一个健康的细胞，一个健康的发细胞，和一个癌变细胞。

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

这一切都与我们耳朵里的这些微的细胞有关。

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

转化通过所谓的细胞来实现。

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

我们有特殊的细胞，它们向我们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.

我已经为各位介细胞有多厉害。

The healthy hair cell divides frequently.

健康的发细胞分裂频繁。

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

所以，当你的细胞健康时，它们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.

所以你会破坏内耳的感知绒细胞，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.

所以降噪实际上确实去除声音，基本上不影响我们的耳细胞。

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

这种设置也使用液体和感觉细胞的组合。

This is exactly what hair cells do.

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细胞的死亡，我们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.

这个器官充满所谓的细胞，每个细胞都有一个微的发状结构伸出来。

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

每个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细胞。
