% ISINAC ACOUSTIC WORLD S.L.U. - ISINAC PLAN ILUCS 40 mm + 400 mm cavity
% Absorption coefficient, one-third octave bands, EN ISO 354.
% Test report: B2019-LACUS-IN-54 II, Fundacion Tecnalia R&I
% Columns: frequency (Hz), absorption coefficient (-). Values may exceed 1 (edge effect).
% Use as an Interpolation function in COMSOL (Ray Acoustics / Acoustic Diffusion Equation).
% alpha_w 0.80 (H) per ISO 11654 clause 4.3. It is strongly recommended to use this single-number rating together with the complete absorption curve. · NO es un bafle suspendido. El informe dice: 'The panels are placed at 400 mm above the floor of the test room, with a distance of 30 mm between them, with the hidden face oriented towards the floor'. Absorbe por UNA cara sobre plenum. Modelarlo como bafle a dos caras duplica el area absorbente.
