Indeed, some toothed whales and bats emit sound pulses around 200,000 hertz and listen for the reflections.

事实上，一些齿鲸和蝙蝠会发出 20 万赫兹左右的声脉冲收听反射声。

Anything in the 1000 hertz range or below.

任何在 1000 赫兹范围内或以下的声。

Researchers observed lip smacking at an average of 4.15 hertz.

What does the nano hertz in NANOGrav refer to explicitly?

NANOGrav 中的“纳赫兹”具体指的是什么？

A biological neuron fires, maybe, at 200 hertz, 200 times a second.

一个生物神元所发出的脉冲率 于 200 赫兹，每秒 200 次。

So nano hertz is the gravitational waves frequency that we're looking at.

“纳赫兹”就是我们正在寻找的引力波率。

Well, baleen whales emit sounds around 14 hertz, the deepest among mammals.

须鲸能发出 14 赫兹左右的声，是哺乳动物中最低沉的。

Parasaurolophus' general resonant frequency as low as 40 hertz, a sound almost as deep as a foghorn.

副栉龙的共振率一般低达40赫兹，这种声几乎和雾角一样低了。

The females are at a much lower pitch. They were around 400 hertz.

HS：女性的高要低得多。 它们的率为 400 赫兹。

[Melany] It's this frequency from about 75 hertz up to about 100 hertz.

- [Melany] 这是从 75 赫兹到 100 赫兹的率。

So he's flying at around 600 hertz.

GG：所以他以 600 赫兹的速度飞行。

Some mid-range Android phones come with 120 hertz screens.

再加十赫兹 慢慢加上去。

When I say watts or hertz, those things are just regular words.

当我说瓦特或赫兹时，那些东西只是常规词。

So in this case that corresponds to one hertz.

所以在这种情况下，它 对应于一赫兹。

The human ear is best at registering sounds above the frequency of 20 hertz.

人耳最擅长记录率高于 20 赫兹的声。

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

The distance between each peak determines the wave's frequency, measured as cycles per second, or hertz.

每个峰之间的距离决定了波的率，以每秒周期数或赫兹来衡量。
