## Octaves from Frequency Formula

The following two example problems outline the steps and information needed to calculate the Octaves from Frequency.

O = log (Fu/Fl) / log (2)

Variables:

- #O is the Octaves from Frequency (number of octaves)
- Fu is the upper frequency (hz)
- Fl is the lower frequency (hz)

## How to Calculate Octaves from Frequency?

The following steps outline how to calculate the Octaves from Frequency.

- First, determine the upper frequency (hz).
- Next, determine the lower frequency (hz).
- Next, gather the formula from above = #O = log (Fu/Fl) / log (2).
- Finally, calculate the Octaves from Frequency.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

upper frequency (hz) = 50

lower frequency (hz) = 30

#O = log (Fu/Fl) / log (2)** **= ?
