Calculation

  1. 1Total absorption A = 250 × 0.2 = 50 m²
  2. 2RT60 = 0.161 × V ÷ A = 0.161 × 500 ÷ 50 = 1.61 s
  3. 3K = 24·ln(10) ÷ c ≈ 0.161 (c ≈ 343 m/s at 20°C)
RT60 is the time for sound to decay 60 dB after the source stops. Sabine formula RT60 = 0.161·V/A works for rooms with mean absorption below about 0.3; for highly absorbing rooms prefer Eyring: RT60 = 0.161·V/[−S·ln(1−ᾱ)]. Total absorption A = Σ Sᵢ×αᵢ; this tool simplifies with a mean coefficient. Recommended values: studio 0.2-0.4 s, living room 0.4-0.8 s, office 0.5-0.7 s, classroom 0.6-0.8 s, concert hall 1.5-2.5 s. Typical coefficients: concrete/tile 0.01-0.03, glass 0.03, wood floor ~0.1, curtains 0.3-0.5, acoustic panels 0.6-0.9. Bare-wall rooms often measure 1-3 s — treat the floor (carpet), windows (heavy curtains) and rear wall (panels) first.
