sci.room-reverberation-Sabine Calculator
Calculates reverberation time with Sabine's formula: RT60 = 0.161 × V / A, where A is total absorption in m² sabins. A 500 m³ classroom absorbing 50 m² sabins: RT60 = 0.161×500/50 = 1.61 s — above the 0.6 s recommendation for speech intelligibility.
Inputs
V M3
Three-dimensional space occupied (m³ or L). 1 m³ = 1,000 L.
S M2
Two-dimensional surface extent (m²). For complex shapes, break into simpler sub-shapes and sum.
Alpha Avg
Age in completed years. Many health and fitness formulas adjust for age.
Results
RT60 Sabine (s)
Sample size or count used in the calculation.
RT60 Eyring correction (s)
Sample size or count used in the calculation.
equivalent absorption area A (m²)
The computed two-dimensional surface area.
RT60 = 0.161·V/(S·ᾱ)
