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

最低的率会到达耳蜗的顶部。

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

最后，它会导致螺旋耳蜗的压力发生变化。

We were just talking to Rebecca Knill, who has a cochlear implant.

我们刚刚采访了装有人工耳蜗的丽贝卡·尼尔 (Rebecca Knill)。

A surface called the basilar membrane runs the length of the cochlea.

称为基底膜的表面贯穿耳蜗的长度。

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

由于内耳的耳蜗管很小，它的听觉也受到了严重的限制。

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

我们有特殊的毛细胞，它们向我们的前庭耳蜗神经发送信号。

We learn in school that the organ of hearing is the coiled, snail-shaped cochlea.

上学时我们曾学过，听觉器官是卷曲的、蜗牛状的耳蜗。

Its motion pushes the fluid within the long chambers of the cochlea.

它的运动推动耳蜗长腔内的液体。

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的人，他们可能需要项手术来植入种称为人工耳蜗的植入物。

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

噪音、疾病、毒素，甚至自然老化都会损害您的耳蜗细胞。

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

雷克斯霸王龙的耳蜗长2.5厘米可接收到很宽的段。

I have 16 electrodes in each of my cochleas.

在我的每个耳蜗中都有 16 个电极。

Those convert the large movements of the eardrum into pressure waves in the fluid of the cochlea.

这些将鼓膜的大运动转化为耳蜗液体中的压力波。

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

由于传递信息的耳蜗细胞较少，传入的声音会产生较弱的神经信号。

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。

Even newer technology like hearing aids or cochlear implants don't work for all or even most Deaf people.

即使是助听器或人工耳蜗等较新的技术也并不适用于所有甚至大多数聋人。

They use pacemakers, insulin pumps, contraceptives, devices to monitor health and disease, and cochlear implants for hearing.

他们使用心脏起搏器、胰岛素泵、避孕药、监测健康和疾病的设备，以及用于听觉的人工耳蜗。

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

那时人造耳蜗对于理解语言的成功率还很低，大概只有 50%。

When you normally hear something, sound waves hit various areas of your ear, creating vibrations that displace fluid inside the cochlea.

当您通常听到某事时，声波会撞击您耳朵的各个区域，产生振动，从而排出耳蜗内的液体。

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

正常大小的耳朵会对20赫兹到20千兹的声音反应，原因在于毛细胞在耳蜗里震动的方式。
