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

耳内有微小的毛胞，可以帮助将声波扫向前方。

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

这样可以使死亡的毛胞复活，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毛胞传输。

This is exactly what hair cells do.

毛胞的作用正是这样。

We use these large hair cells from a frog for many of our experiments.

我们在许多实验中都采用这些取青蛙的型毛胞。

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肝胞，一个健康的毛发胞，和一个胞。

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小的毛胞有关。

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

转化通过所谓的毛胞来实现。

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

我们有特殊的毛胞，它们向我们的前庭耳蜗神经发送信号。

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

每个毛胞会放并汇报某个特定频率，而忽略所有其他频率。

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

每一个毛胞都附着在神经系统的轴突上。

The healthy hair cell divides frequently.

健康的毛发胞分裂频繁。

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了声音，基本上不影响我们的耳毛胞。

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

所以，当你的毛胞健康时，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毛胞，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.

巨的声音会损坏这些毛胞，从而导致暂时性，甚至是永久性听力损失。

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

这种设置也使用了液体和感觉毛胞的组合。

And these emissions constitute a really strong demonstration of just how active the hair cell can be.

这些被释放的声音非常有力地展示了毛胞有多活跃。

Because it doesn't use reactions, the hair cell is fully 1,000 times faster than our other senses.

因为毛胞不使用化学反应，它比我们的其他感官要快整整 1000 倍。

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胞的死亡，我们称之为感音神经性听力损失。
