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

但声带也在基本频率大震动之上了一系列小振动。

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.

正在创造一个大约 262 赫兹基音或基频，因为声带每秒来回振动 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.

但对于一端封管道，您不能将基频加倍或四倍——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.

第一部分振动频率基本频率两倍。下一个部分基频三倍，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.

这因为它们都在同基频，即它们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，尽管这个基频实际上并不存在，但确实听到了它。

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

每个谐波频率等于 谐波数乘以基频。

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频数量， 得到谐波频率。

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

谐波数量等于乘以数量 通过基频，求出谐波频率。

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

对于许多乐器而言，最常见泛音基频整数倍。

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频七倍八个频率仓。

Which is twice the fundamental frequency.

这等于基频两倍。

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

两端固定驻波频率为 谐波数乘以基频。

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 基本频率，带音调。
