## Room Resonant Frequency Formula

The following two example problems outline the steps and information needed to calculate the Room Resonant Frequency.

**RRF = 1130 / (2*L)**

Variables:

- RRF is the Room Resonant Frequency (hz)
- L is the length of the longest dimension of the room (ft)

## How to Calculate Room Resonant Frequency?

The following steps outline how to calculate the Room Resonant Frequency.

- First, determine the length of the longest dimension of the room (ft).
- Next, determine the ${V2}.
- Next, gather the formula from above = RRF = 1130 / (2*L).
- Finally, calculate the Room Resonant 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.

length of the longest dimension of the room (ft) = 15

RRF = 1130 / (2*L)** **= ?
