Acoustics — Determination and application of measurement uncertainties in building acoustics — Part 2: Sound absorption

OVERVIEW

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.
