Enter the length of the longest dimension of the room (ft) and the ${V2} into the Room Resonant Frequency Calculator. The calculator will evaluate the Room Resonant Frequency. ## Room Resonant Frequency Formula The following two example problems outline the steps and information needed to calculate the Room Resonant Frequency. RRF = 1130 / (2*L) Variables: • RRF is the Room Resonant Frequency (hz) • L is the length of the longest dimension of the room (ft) ## How to Calculate Room Resonant Frequency? The following steps outline how to calculate the Room Resonant Frequency. 1. First, determine the length of the longest dimension of the room (ft). 2. Next, determine the${V2}.
3. Next, gather the formula from above = RRF =  1130 / (2*L).
4. Finally, calculate the Room Resonant Frequency.
5. 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) = ?
