sci.room-reverb-rt60-sabine Calculator
Calculates room reverberation time using Sabine's formula: RT60 = 0.161V/A, where V is volume and A is total absorption in sabins. A 500 m³ classroom with A = 50 m² sabins has RT60 = 1.6 s — above the 0.6 s target for speech, indicating inadequate acoustic treatment.
Inputs
Room Volume M3
Three-dimensional space occupied (m³ or L). 1 m³ = 1,000 L.
Avg Absorption Coeff
Age in completed years. Many health and fitness formulas adjust for age.
Total Surface Area M2
Two-dimensional surface extent (m²). For complex shapes, break into simpler sub-shapes and sum.
Results
RT60 Sabine (s)
Sample size or count used in the calculation.
RT60 Eyring (s)
Sample size or count used in the calculation.
absorption area A (m²)
The computed two-dimensional surface area.
