Sabine Reverberation Estimate

How to use this tool

1. Estimate decay time and the additional absorption needed to reach a target RT60.
2. Set room volume, equivalent absorption area, target rt60 in the indicated units.
3. Calculate and compare estimated rt60, additional equivalent absorption.

Try this example

{
  "volume": 100,
  "absorption": 20,
  "target": 0.5
}

Accuracy and scope

Diffuse-field Sabine approximation with uniform weak absorption; not a substitute for acoustic measurement.
