频率是每单位时间重复事件的发生数量。它是在赫兹（Hz）中测量的。
1 oct = 2,000,000 μHz
1 μHz = 5.0000e-7 oct
例子:
将15 八度转换为Microhertz：
15 oct = 30,000,000 μHz
| 八度 | Microhertz |
|---|---|
| 0.01 oct | 20,000 μHz |
| 0.1 oct | 200,000 μHz |
| 1 oct | 2,000,000 μHz |
| 2 oct | 4,000,000 μHz |
| 3 oct | 6,000,000 μHz |
| 5 oct | 10,000,000 μHz |
| 10 oct | 20,000,000 μHz |
| 20 oct | 40,000,000 μHz |
| 30 oct | 60,000,000 μHz |
| 40 oct | 80,000,000 μHz |
| 50 oct | 100,000,000 μHz |
| 60 oct | 120,000,000 μHz |
| 70 oct | 140,000,000 μHz |
| 80 oct | 160,000,000 μHz |
| 90 oct | 180,000,000 μHz |
| 100 oct | 200,000,000 μHz |
| 250 oct | 500,000,000 μHz |
| 500 oct | 1,000,000,000 μHz |
| 750 oct | 1,500,000,000 μHz |
| 1000 oct | 2,000,000,000 μHz |
| 10000 oct | 20,000,000,000 μHz |
| 100000 oct | 200,000,000,000 μHz |
