Room Mode Calculator

Calculate reverberation time (RT60) using the Sabine and Eyring equations. Input room dimensions and surface materials to get RT60, total absorption, and comparison to optimal values.

Inputs

Room length (m)

Room width (m)

Room height (m)

Room purpose (0-4)

Wall material (0-4)

Floor material (0-3)

Ceiling material (0-3)

Tab to move between fields

How to Use This Calculator

Enter Room length (m), Room width (m), and Room height (m).
Set Room purpose (0-4), Wall material (0-4), and Floor material (0-3).
Adjust Ceiling material (0-3) as needed.
Review the RT60 Sabine (s) result.
Use RT60 Eyring (s) and Optimal RT60 (s) to inform your decision.
