I have 16 electrodes in each of my cochleas.

在我每个耳蜗中都有 16 个电极。

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

我有殊毛细胞，它向我前庭耳蜗神经发送信号。

Loud noises, diseases, toxins, and even natural aging can damage your cochlear cells.

巨大声音、疾病、都可能会损害你耳蜗细胞。

It turns out there's a similar process at play in your cochlea, deep inside your ear- where a tiny bony cavity houses the organ that allows you to hear.

结果表明，你耳朵深处耳蜗中也发生着类似过程，那里有微型骨腔，容纳着让我听到声音器官。

Next, the sound makes its way to the cochlea, which is a hollow, spiraled bit of bone that's full of fluid and lined with thousands of microscopic hairs.

接下来，声音进入耳蜗，耳蜗是空心、螺旋骨头，里面充满了液体，并有成千上万细绒毛。

Kind of like a harp with many, many strings, the fibers near the base of the cochlea are short and stiff, while those at the end are longer and looser.

有点像有多多弦竖琴，耳蜗底部附近纤维又短又硬，而末端纤维又长又松。

A full-sized ear responds to frequencies between 20 hertz and 20 kilohertz, because of how the hair cells in our cochlea vibrate.

正常大小耳朵会对20赫兹到20千兹声音反应，原因在于毛细胞在耳蜗里震动方式。

The cochlea in a Tyrannosaurus Rex is 2.5 centimetres long, so it can pick up a wide range of frequencies.

雷克斯霸王龙耳蜗长2.5厘米可接收到频段。

The success rate then for speech comprehension was low, maybe 50 percent.

那时人造耳蜗对于理解语言成功率还低，大概只有 50%。

For those who can't hear even with a device, they might have an operation to put in something called a cochlear implant.

对于那些即使使用设备也听不到声音人，他可能需要进行一项手术来植入一种称为人工耳蜗植入物。

Today your ears heard me tell you how your cochlea, basilar membrane, and hair cells register and transduct sound into action potentials.

今天你耳朵听到我告诉你你耳蜗、基底膜和毛细胞是如何记录声音并将声音转化为动作电位。

And its hearing is severely limited, as the cochlea duct inside the inner ear is tiny.

由于内耳耳蜗管小，它听觉也受到了严重限制。

If you could unspool this little snail shell, and cut it in a cross-section, you'd see that the cochlea consists of three main chambers that run all the way through it, separated by sensitive membranes.

如果你能打开这个小蜗牛壳，并把它切成一个横截面，你会看到耳蜗由三个贯穿耳蜗主要腔室组成，它被敏感膜隔开。

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，连续音调在耳蜗表面表达位置相隔几十个毛细胞。

The lowest frequencies go all the way up to the top of the cochlea.

最低频率会到达耳蜗顶部。

The highest frequencies, down to 20,000 Hz, go all the way to the bottom of the cochlea, and every other frequency is represented somewhere in between.

高达 2 万赫兹最高频率则会到达耳蜗底部，所有其他频率都在中间某个地方表示出来。

In this picture, you can see where three notes — middle C and the two extreme notes on a piano — are represented in the cochlea.

在这张图里，你可以看见三个音符 —— 中央 C 和钢琴两端音符 —— 在耳蜗内部被呈现位置。

The number one question that I get about the cochlear implant when people hear about the magnets is whether my head sticks to the refrigerator.

当人听说人工耳蜗会用到磁铁时候，问我最多一个问题就是：我头会不会被吸到冰箱上去。

With fewer cochlear cells relaying information, incoming sounds generate weaker nerve signals.

由于传递信息耳蜗细胞较少，传入声音会产生较弱神经信号。

And finally, it causes pressures to change in the spiraling cochlea.

最后，它会导致螺旋耳蜗压力发生变化。
