🏛️ Reverberation Time Calculator
Calculate room acoustics and reverberation time for different frequencies
📐 Reverberation Time Formulas
RT₆₀ = 0.161 × V/(A × α)
A = S₁α₁ + S₂α₂ + ... + Sₙαₙ
α_avg = A/S_total
RT₆₀ = 0.161 × V/(S × α_avg)
RT₆₀ = reverberation time, V = volume, A = total absorption, S = surface area, α = absorption coefficient

💡 Tips & Information
- RT₆₀ = time for sound to decay 60 dB
- Optimal RT: Concert halls (1.5-2.5s), Studios (0.2-0.5s)
- Lower frequencies need more absorption
- Soft materials increase absorption
- Room shape affects sound distribution
