Reverberation time — how long a sound takes to decay by 60 dB — is set by Sabine's formula RT60 = 0.161·V/(S·α). Big, hard rooms ring for seconds; small, soft rooms deaden almost instantly. Concert halls target around 2 seconds; recording studios far less. Adding absorption pulls the decay down.

Governing equation

RT_{60} = \frac{0.161 V}{A} = \frac{0.161 \times 200}{33} = 0.98 s, A = i \sum α_{i} S_{i} = 33 sabins

Reading this result: RT60 of 0.98 s is a balanced living-room decay: speech stays clear with a touch of warmth.

About this simulation

The full Reverb Time (Sabine) tool models an organ pipe with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
