Which is twice the fundamental frequency.

等于基频的两倍。

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

但是你的声也在基本频率的震动之上产生了系列的小振动。

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，音调。

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

每谐波的频率等于 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.

谐波的数量等于您乘以基频的数量， 得到谐波的频率。

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.

你正在创造约 262 赫兹的基音或基频，因为你的声每秒来回振动 262 次。

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

谐波的数量等于你乘以的数量 通过基频，求出谐波的频率。

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

第部分的振动频率是基本频率的两倍。下部分是基频的三倍，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.

两端固定的驻波的频率为 谐波数乘以基频。

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.

但是对于端封闭的管道，您不能将基频加倍或四倍——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，如果信号由八样本组成，则变换具有从零到基频七倍的八频率仓。
