Which is twice the fundamental frequency.

这等两倍。

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

但是你声带也在本率大震动之上产生了一系列小振动。

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

吉他也调整以响应 本率，带音调。

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 谐波数以。

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

谐波数量等以数量， 得到谐波率。

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.

你正在创造一个大约 262 赫兹音或，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.

谐波数量等你以数量 通过，求出谐波率。

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

第一部分振动率是本率两倍。下一个部分是三倍，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.

两端固定驻波率为 谐波数以。

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.

但是对一端封闭管道，不能将加倍或四倍——或以任何偶数。
