But your vocal chords are also producing a bunch of little vibrations on top of that big vibration of the fundamental frequency.

但是你声带也在基本率大震动之上产生了小振动。

You're creating a base tone or fundamental frequency at about 262 hertz because your vocal chords are vibrating back and forth 262 times a second.

你正在创造个大约 262 赫兹基音或基，因为你声带每秒来回振动 262 次。

But for a pipe that’s closed on one end, you can’t double the fundamental frequency, or quadruple it -- or multiply it by any even number.

但是对于端封管道，您不能将基加倍或四倍——或乘以任何偶数。

The first partial vibrates at twice the frequency of the fundamental. The next partial is three times the fundamental’s frequency, and so on.

第部分振动率是基本率两倍。下个部分是基倍，依此类推。

That's because they're both producing the same fundamental frequency, that is the lowest and usually highest amplitude vibration they produce.

这是因为它们都在产生相同基，即它们产生最低且通常振幅最高振动。

So you actually heard this fundamental frequency, even though it wasn't there.

因此，尽管这个基实际上并不存在，但你确实听到了它。

Because, remember: the frequency of each harmonic is equal to the number of the harmonic, times the fundamental frequency.

每个谐波率等于 谐波数乘以基。

The number of a harmonic is equal to the number you multiply by the fundamental frequency, to get the harmonic’s frequency.

谐波数量等于您乘以基数量， 得到谐波率。

The number of a harmonic is equal to the number you multiply by the fundamental frequency, to get the harmonic's frequency.

谐波数量等于你乘以数量 通过基，求出谐波率。

For a lot of instruments, the most common overtones are integer multiples of the fundamental frequency.

对于许多乐器而言，最常见泛音是基整数倍。

So if the signal is made up of eight samples, then the transform has eight frequency bins going from zero up to seven times the fundamental frequency.

因此，如果信号由八个样本组成，则变换具有从零到基七倍八个率仓。

Which is twice the fundamental frequency.

这等于基两倍。

The frequency of a standing wave with two fixed ends will just be equal to the number of the harmonic, times the fundamental frequency.

两端固定驻波率为 谐波数乘以基。

Guitars are also tuned so that the fundamental frequencies of their strings, correspond to set notes.

吉他也被调整以响应 基本率，带音调。
