Enter the volume of the room (ft^3) and the total area of absorption (sabins) into the Calculator. The calculator will evaluate the Reverberation Time. 

Reverberation Time Formula

RT = .049 * (V/A)

Variables:

  • RT is the Reverberation Time (sec)
  • V is the volume of the room (ft^3)
  • A is the total area of absorption (sabins)

To calculate Reverberation Time, divide the volume of the room by the total area of absorption, then multiply by .049.

How to Calculate Reverberation Time?

The following steps outline how to calculate the Reverberation Time.

  1. First, determine the volume of the room (ft^3). 
  2. Next, determine the total area of absorption (sabins). 
  3. Next, gather the formula from above = RT = .049 * (V/A).
  4. Finally, calculate the Reverberation Time.
  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.

the volume of the room (ft^3) = 500

the total area of absorption (sabins) = 7.5
