Sabine's Formula
Formula
RT60 = 0.161 × V / A
Where:
- • RT60 = reverberation time (s)
- • V = room volume (m³)
- • A = total absorption (sabins)
- • 0.161 = 4 × ln(10⁶) / c (for c = 343 m/s)
Typical RT60 Values
- • Recording studio: 0.2-0.4 s
- • Concert hall: 1.5-2.5 s
- • Church: 2-4 s
- • Large hall: 3-5 s
