赫兹，是国际单位制中频率的单位，它是每秒钟的周期性变动重复次数的计量。 赫兹简称赫。 每秒钟振动（或振荡、波动）一次为1赫兹，或可写成次/秒，周/秒。 因德国科学家赫兹而命名。

频率指单位时间内完成周期性变化的次数，常用符号f或u表示，单位为秒分之一，频率单位有Hz、KHz、MHz、GHz、THz。 频率与周期对应关系：频率=1/周期。

在各个视频网站如果搜“432Hz”的话，能找到很多视频，里边会把各种音乐的标准音高调到432Hz，因为有人觉得432Hz的标准音听起来更好听。 但是也有一些人觉得，调整音高不只是出于对声音偏好的考究。 有一些博客写到标准的440Hz调音对健康不利，但是你的想象力能cover到，这和那翠（Nazi）也能扯上关系吗？ “ 近期通过对宇宙振动本质的再发现表明，目前使用的标准音高可能会产生对健康的不利影响，或者使人类意识中出现反社会行为……有一种说法，把标 …

赫兹 (Hz) 是频率的单位，表示每秒的周期数。 一个赫兹 (1 Hz) 意味着每秒发生一次周期性事件。 例如，如果一个摆动每秒钟完成一次完整的振动，那么这个摆动的频率就是1 Hz。

This online tone generator plays a tone at 43 Hertz (Hz) when the "Start" button is clicked. You can change the frequency of the tone by moving the slider or entering your desired frequency into the text box above. Humans can typically hear sounds in the 20 Hz to 20 kHz range, although adults tend to lose their ability to hear sounds past 15 kHz.

I have created a Note Frequency Chart that you for example can use to perfectly tune your instruments and sounds to the key of your song, sound design etc. The note frequency guide is based on the standard 12-tone Equal Tempered Tuning System (A = 440Hz). PS.
