But curiously, the frequency of their purrs, between 25 and 150 hertz, is within a range that can promote tissue regeneration.

可是，奇怪的是打呼噜的频率，在25-150赫兹之间，这个范内能促进组织再生。

For people, the average CFF is 60 hertz (ie, 60 times a second).

对人类来说，平均的CFF是60赫兹（即，每秒六十次）。

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

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。

So in Japan for example, I think one of the main islands is at 60 hertz and the other half of Japan is at 50 hertz.

以日本为例，我觉得其一个主要岛屿的电流频率是60赫兹，而日本另一半地方的电流频率就是50赫兹。

In the US power is at 60 hertz and in the UK it's around 50 hertz.

在美国电力下，电流频率是60赫兹，在英国是50赫兹左右。

The console itself runs a 1.2 G hertz processor, a modified version of android 2.2, and would come with a TV remote and game controller.

这款游戏机配置有1.2 G赫兹处理器，运行修版的安卓2.2系统，并配有一个电视遥控器和游戏手柄。

So Grover built a free website where users can upload recordings of the instrument, from their smartphone or computer, and analyze the hertz.

因此，格罗弗建立一个免费网站，用户可以用智能手机或电脑上传仪器的录音，并分析声音赫兹。

Full-sized human voices fall between 85 and 255 Hz, but my inner ear is so small, I can't hear anything less than maybe four or five hundred hertz.

成人的声音在85到255 Hz，但是我的内耳太小，听不到小于400或500 Hz 的声音。

I'm pretty sure when I go to the United States, my electric toothbrush doesn't charge up at 60 hertz - 110 volts, but my laptop still works.

我可以肯定的是，当我去美国的时候，我的电动牙刷在60赫兹，110伏电压下没法充电，但我的笔记本电脑仍能用。

Standard frequency in the US is 60 hertz, actually I think in the US on the mainland, US main continent, there are three different synchronous areas.

美国的电流标准频率是60赫兹，实际上我认为在美国陆有三个电流频率相同的不同地区。

So although it's around 60 hertz, at any moment in time these three different areas, because they're not connected to each other, will be going at a slightly different frequency.

所以尽管其电流频率都在60赫兹左右，但在任何时刻，由于这三个地区彼此不相连，它们的电流频率会稍有不同。

Indeed, my laboratory and others have shown that in people with Alzheimer's and in laboratory mice that model the disease, gamma waves at the frequency of 40 hertz have reduced power and synchrony than they should be.

我的研究和其他发现目前证实在阿兹海默症人群中以及研究中实验组的小白鼠中，40赫兹频率的伽玛波其强度和一致性均遭到削弱。
