你们听到声音，你的鼓膜以相同频率,开始震动,然后听到我的音调。
They reach you, your eardrum starts to oscillate with the same frequency and you hear that tone.
此前乔瓦·尼巴。蒂斯塔·贝内代蒂(1530 - 1590)有相关的振动频率比和音调比之间的关系的理论。
Earlier Giovanni Battista Benedetti (1530-1590) had related the ratio of pitches to the ratio of the frequencies of vibrating objects.
即使是一把吉他上一个简单的音节都有一系列的谐振频率，而这一系列的谐振频率都有着特殊的谐振关系，这也正是为什么我们听到的只是某一音调上的一个单音。
Even a simple note on my guitar has an array of harmonic frequencies. But the frequencies have a special harmonic relationship, which is why you hear it as a single sound with a single pitch.
