Acoustics. Determination and application of measurement uncertainties in building acoustics -- Sound absorption
This document specifies how to calculate:
the uncertainty of sound absorption coefficients and equivalent sound absorption areas measured according to ISOÂ 354 ;
the uncertainty of the practical and weighted sound absorption coefficients determined according to ISOÂ 11654 ;
the uncertainty of the object sound absorption coefficient according to ISOÂ 20189 ; and
the uncertainty of the single number rating determined according to ENÂ 1793-1 .
Furthermore, the use of uncertainties in reporting measured or weighted sound absorption coefficients is explained.
