Reverb Time Calculator

Calculate the reverb time (RT60) of a room based on its volume and absorption coefficients

Input Parameters

Calculation Results

Calculation Formula

RT60 = 0.163 × V / A

Where:
RT60 = Reverb time (seconds)
V = Room volume (m³)
A = Total absorption (m² Sabine)

Learn how to use the Reverb Time Calculator to analyze room acoustics

How to Use the Calculator

  1. Enter the Room Volume in cubic meters (m³). This is the total space of the room.
  2. Enter the Total Absorption in square meters of Sabine absorption units. This represents the total sound-absorbing materials in the room.
  3. Click the Calculate button to compute the reverb time.
  4. The result will be displayed in seconds (RT60).

Understanding Reverb Time (RT60)

Reverb time (RT60) is the time it takes for sound to decay to 60% of its original intensity in a space. It's a key parameter in room acoustics and audio engineering.

Example

For a room with a volume of 100 m³ and total absorption of 25 m² Sabine:

RT60 = 0.163 × 100 / 25 = 6.52 seconds
