Description: Physical and Acoustic variables describing 12 churches. Some models fit: T = b0 + b1(1/V) + b2(1/V^2) + b3(1/V^3) EDT = b0 + b1((V/ST)^-1 + b2(V/ST)^-2 + b3(V/ST)^-3 TS = b0 +b1H + b2H^2 + b3H^3 G = b0 + b1(1/V) + b2(1/V^2) + b3(1/V^3) C80 = b0 + b1((V/ST)^-1 + b2(V/ST)^-2 + b3(V/ST)^-3 C50 = b0 +b1H + b2H^2 + b3H^3 D50 = b0 + b1((V/ST)^-1 + b2(V/ST)^-2 + b3(V/ST)^-3 RASTI = b0 + b1((V/ST)^-1 + b2(V/ST)^-2 + b3(V/ST)^-3 Variables/Labels Church (church) Volume in m^3 (V) Length in m (L) Width in m (W) Average height in m (H) Total surface in m^2 (ST) Total ground surface in m^2 (SG) Volume/ground surface in m^(3/2) V_SG Reverberation Time in sec (T) Early Decay Time in sec (EDT) centre time in ms (Ts)Sound Strength in dB (G) Clarity in dB (C80) Clarity for speech in dB (C50) Clarity for Definition in percent (D50) Early Lateral Energy Fraction in percent (LF) RASTI Index (RASTI)
