Enter the volume of the room and the total absorption into the calculator to determine the reverb time. This calculator can also evaluate any of the variables given the others are known.
Reverb Time Formula
The following formula is used to calculate the reverb time.
T = 0.1611 * V / A
Variables:
- T is the reverb time in seconds
- V is the volume of the room in cubic meters
- A is the total absorption of the room in sabins
To calculate the reverb time, multiply the volume of the room by 0.1611. Then divide the result by the total absorption of the room. The result is the reverb time in seconds.
What is a Reverb Time?
Reverb time, also known as reverberation time or RT60, is a measure of the time it takes for the sound to decay by 60 decibels after the source of the sound has stopped. It is a key factor in the acoustics of a room or space, affecting how we perceive sound in that environment. Longer reverb times can make a room sound more echoey or hollow, while shorter reverb times can make it sound more dead or flat.
How to Calculate Reverb Time?
The following steps outline how to calculate the Reverb Time using the given formula:
- First, determine the volume of the room (V) in cubic meters.
- Next, determine the total absorption of the room (A) in sabins.
- Next, gather the formula from above: T = 0.1611 * V / A.
- Finally, calculate the Reverb Time (T) using the formula.
- 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:
Volume of the room (V) = 50 cubic meters
Total absorption of the room (A) = 10 sabins
