Acoustics - Determination and application of measurement uncertainties in building acoustics - Part 2: Sound absorption (ISO 12999-2:2020)

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.

Akustik - Bestimmung und Anwendung der Messunsicherheiten in der Bauakustik - Teil 2: Schalldämpfung (ISO 12999 2:2020)

Dieses Dokument legt fest, wie Folgendes zu berechnen ist:
—   die Unsicherheit von nach ISO 354 gemessenen Schallabsorptionsgraden und äquivalenten Schall-absorptionsflächen;
—   die Unsicherheit der nach ISO 11654 ermittelten praktischen und bewerteten Schallabsorptionsgrade;
—   die Unsicherheit des Schallabsorptionsgrades einzelner Objekte nach ISO 20189;
—   die Unsicherheit der nach EN 1793 1 ermittelten Einzahl Angabe.
Des Weiteren wird die Verwendung von Unsicherheiten bei der Angabe von gemessenen oder bewerteten Schallabsorptionsgraden erläutert.

Acoustique - Détermination et application des incertitudes de mesure dans l'acoustique des bâtiments - Partie 2: Absorption acoustique (ISO 12999-2:2020)

Le présent document spécifie comment calculer:
—          l'incertitude des coefficients d'absorption acoustique et des aires d'absorption acoustique équivalentes mesurés conformément à l'ISO 354;
—          l'incertitude des coefficients d'absorption acoustique pratiques et pondérés déterminés conformément à l'ISO 11654;
—          l'incertitude du coefficient d'absorption acoustique d'un objet conformément à l'ISO 20189; et
—          l'incertitude de l'indice unique d'évaluation déterminé conformément à l'EN 1793-1.
Il explique également comment utiliser les incertitudes pour consigner dans le rapport les coefficients d'absorption acoustique mesurés ou pondérés.
