Reverberation Time Calculator

Formula

The formula to calculate the Reverberation Time is:

$RT = 0.049 \times \left( \frac{V}{A} \right)$

Where:

$RT$ is the Reverberation Time (sec)
$V$ is the volume of the room (ft³)
$A$ is the total area of absorption (sabins)

What is Reverberation Time?

Reverberation Time (RT) is the time it takes for sound to decay by 60 decibels in a closed space. It is a critical parameter in acoustics, affecting the clarity and quality of sound in a room. The RT depends on the volume of the room and the total area of sound-absorbing materials within it.

Example Calculation

Let's assume the following values:

Volume of the Room (V) = 5000 ft³
Total Area of Absorption (A) = 250 sabins

Using the formula:

$RT = 0.049 \times \left( \frac{5000}{250} \right) = 0.98 \text{ seconds}$

The Reverberation Time (RT) is 0.98 seconds.
