RT60 Reverberation Calculator
Estimate a room's reverberation time from its dimensions.
Uses the Sabine equation to compute the reverberation time (RT60) of a room from its volume and total absorption. Rough-and-ready — accurate enough to spec panels; use a phone app for on-site validation.
Estimated RT60
0.35 s
Target for this room type: 0.6 s
Under target by 0.25 s — room may sound too dead.
Room volume: 90 m³
Treated surface area: 38 m²
Approximation only — assumes NRC 0.85 on treated surfaces and 0.10 on untreated ones. For accurate on-site measurement use a phone app such as REW or Auditor. For a spec-grade estimate, send us the room brief.
For a spec-grade number
Send us the room.
Our acoustic engineers do the room-tuned calculation and return it within 24 hours — no charge.
