🎙️ Sabine Equation RT60 (0.5-0.8s Target for Speech), NRC 0.85 Acoustic Baffles

Room Acoustics RT60 Reverberation Calculator

Calculate architectural room reverberation and sound absorption using the Sabine equation: calculate RT60 decay time (target 0.5 to 0.8 seconds for conference rooms and classrooms), total room absorption Sabins (based on drywall, glass, and carpet absorption coefficients), required NRC 0.85 acoustic wall panels/baffles, and AV contractor margins.
