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

最低频率会到达耳顶部。

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

最后，它会导致螺旋耳压力发生变化。

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耳长度。

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

由于内耳耳管很小，它听觉也受到了严重。

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

它运动推动耳长腔内液体。

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

对于那些即使使用备也听不到声音人，他们可能需要进行一项手术来入一种称为人工耳入物。

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

由于传递信息耳细胞较少，传入声音会产生较弱神经信号。

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

雷克斯霸王龙耳长2.5厘米可接收到很宽频段。

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耳细胞。

I have 16 electrodes in each of my cochleas.

在我每个耳中都有 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耳液体中压力波。

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

那时人造耳对于理解语言成功率还很低，大概只有 50%。

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、牛状耳。

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等较新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、监测健康和疾病备，以及用于听觉人工耳。

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，连续音调在耳表面表达位置相隔几十个毛细胞。

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，声波会撞击您耳朵各个区域，产生振动，从而排出耳内液体。

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

正常大小耳朵会对20赫兹到20千兹声音反应，原因在于毛细胞在耳里震动方式。

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、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。
