Reverberation Time Calculator
Introduction
Calculating reverberation time is crucial in various fields, such as architecture, audio engineering, and room acoustics. Reverberation time, often denoted as RT60, measures the time it takes for sound to decay by 60 decibels in a space after the sound source stops emitting. This article presents a simple yet accurate reverberation time calculator.
How to Use
To use the reverberation time calculator, input the values of the room’s volume (V) and the total absorption (A) of the surfaces within the room. Then, click the “Calculate” button to obtain the reverberation time.
Formula
The formula for calculating reverberation time (RT60) is:

Where:
- RT60 = Reverberation time in seconds
- V = Volume of the room in cubic meters (m³)
- A = Total absorption of surfaces in the room in sabins (m²)
Example Solve
Suppose we have a room with a volume of 1000 m³ and a total absorption of 200 sabins. Using the formula:

Thus, the reverberation time for this room would be approximately 0.245 seconds.
