Resumen
This document specifies how to calculate:
— the uncertainty of sound absorption coefficients and equivalent sound absorption areas measured according to ISO 354;
— the uncertainty of the practical and weighted sound absorption coefficients determined according to ISO 11654;
— the uncertainty of the object sound absorption coefficient according to ISO 20189; and
— 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.
