Acoustics. Sound absorbers for use in buildings. Rating of sound absorption1 Scope 1. 1 This International Standard specifies a method by which the frequency dependent values of the sound absorption coefficient can be converted into a single number. Before this is done, the one third octave band values of the sound absorption coefficient measured in accordance with ISO 354 are converted into octave bands. In annex a classification method, based on these single numbers, is given for information.
