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

最低频率会到达顶部。

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

最后，它会导致螺旋压力发生变化。

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

我们刚刚采访了装有人工丽贝卡·尼尔 (Rebecca Knill)。

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

称为基底膜表面贯穿长度。

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

由于内管很小，它听觉也受到了严重限制。

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

我们有特殊毛细胞，它们向我们前庭神经发送信号。

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、牛状。

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

它运动推动长腔内液体。

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人，他们可能需要进行一项手术来植入一种称为人工植入物。

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

噪音、疾病、，至自然老化都会损害您细胞。

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

雷克斯霸王龙长2.5厘米可接收到很宽频段。

I have 16 electrodes in each of my cochleas.

在我每个中都有 16 个电极。

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

这些将鼓膜大运动转化为液体中压力波。

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

由于传递信息细胞较少，传入声音会产生较弱神经信号。

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，连续音调在表面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等较新技术也并不适用于所有至大多数聋人。

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、胰岛泵、避孕药、监测健康和疾病设备，以及用于听觉人工。

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

那时人造对于理解语言成功率还很低，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，声波会撞击您朵各个区域，产生振动，从而排出内液体。

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

正常大小朵会对20赫兹到20千兹声音反应，原因在于毛细胞在里震动方式。
