% ISINAC ACOUSTIC WORLD S.L.U. - ISINAC ELYPSIUM aleatorio ILUCS 305 mm
% Absorption coefficient, one-third octave bands, EN ISO 354.
% Test report: B2019-LACUS-IN-83 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).
% Free-standing object. alpha_obj = A_obj(f) / S with S = 2.44 m2 as declared in the test report. Per-third-octave values are computed BY ISINAC from the measured A_obj; the laboratory publishes alpha_obj in octave bands only. Model the enclosing surface of the object, not a wall, and use exactly that S.
