This document specifies how to calculate:

  1. the uncertainty of sound absorption coefficients and equivalent sound absorption areas measured according to ISO 354 ;

  2. the uncertainty of the practical and weighted sound absorption coefficients determined according to ISO 11654 ;

  3. the uncertainty of the object sound absorption coefficient according to ISO 20189 ; and

  4. the uncertainty of the single number rating determined according to EN 1793-1 .

Furthermore, the use of uncertainties in reporting measured or weighted sound absorption coefficients is explained.
