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

你声带也在基本大震动之上产生了一系列小振动。

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

对于许多乐器来说，最常见泛音基整数倍。

(sample sound buzzing) So you actually heard this fundamental frequency, even though it wasn't there.

（样本声音嗡嗡声）因此，尽管这个基不存在，您实际上听到了它。

Which is twice the fundamental frequency.

这等于基两倍。

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

这因为它们都产生相同基，即它们产生最低且通常最高振幅振动。

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

每个谐波等于 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，带音调。

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.

你正在创造一个大约 262 赫兹基音或基，因为你声带每秒来回振动 262 次。

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。

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。

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

第一部分振动基本两倍。下一个部分基三倍，依此类推。

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

两端固定驻波为 谐波数乘以基。

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.

对于一端封闭管道，您不能将基加倍或四倍——或乘以任何偶数。

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仓。
