Acoustics - Test methods for the qualification of the acoustic environment - Part 2: Determination of the environmental correction (ISO 26101-2:2024)
This document specifies methods for qualifying an environment that approximates to an acoustic free field near one or more reflecting planes. The goal of the qualification is to determine the environmental correction , which is used to correct for reflected sound when determining the sound power level or sound energy level of a noise source from sound pressure levels measured on a surface enveloping the noise source (machinery or equipment) in such an environment.
In practice, the value determined will be a function of both the reflected sound from the test environment and the shape and size of the measurement surface used for the determination. For the purposes of this document and the documents that refer to it, the differences between values determined with different measurement surfaces are assumed to be included in the stated measurement uncertainty for the test method.
Akustik - Prüfverfahren zur Qualifizierung der akustischen Umgebung - Teil 2: Bestimmung der Umgebungskorrektur (ISO 26101-2:2024)
Dieses Dokument legt Verfahren zur Qualifizierung einer Umgebung fest, die sich einem akustischen Freifeld in der Nähe einer oder mehrerer reflektierender Ebenen annähert. Ziel der Qualifizierung ist es, die Umgebungskorrektur K2 zu bestimmen, die zur Korrektur des reflektierten Schalls bei der Bestimmung des Schallleistungspegels oder des Schallenergiepegels einer Geräuschquelle aus Schalldruckpegeln verwendet wird, die an einer die Geräuschquelle (Maschinen oder Geräte) umgebenden Oberfläche in einer solchen Umgebung gemessen werden.
In der Praxis wird der bestimmte K2-Wert eine Funktion sowohl des von der Messumgebung reflektierten Schalls als auch der Form und Größe der für die K2-Bestimmung verwendeten Messfläche sein. Für die Anwendung dieses Dokuments und der Dokumente, die sich darauf beziehen, wird davon ausgegangen, dass die Unterschiede zwischen den mit verschiedenen Messflächen bestimmten K2-Werten in der angegebenen Messunsicherheit für das Prüfverfahren enthalten sind.
Acoustique - Méthodes d’essai pour la qualification de l'environnement acoustique - Partie 2: Détermination de la correction d’environnement (ISO 26101-2:2024)
Le présent document spécifie des méthodes de qualification d’un environnement qui se rapproche d’un champ acoustique libre à proximité d’un ou de plusieurs plans réfléchissants. L’objectif de la qualification est de déterminer la correction d’environnement , qui est utilisée pour corriger le bruit réfléchi lors de la détermination du niveau de puissance acoustique ou du niveau d’énergie acoustique d’une source de bruit à partir des niveaux de pression acoustique mesurés sur une surface enveloppant la source de bruit (machine ou équipement) dans un tel environnement.
En pratique, la valeur déterminée dépend aussi bien du son réfléchi par l’environnement d’essai que de la forme et de la taille de la surface de mesure utilisée pour la détermination de . Pour les besoins du présent document et des documents qui y font référence, les différences entre les valeurs de déterminées avec différentes surfaces de mesure sont réputées être incluses dans l’incertitude de mesure déclarée pour la méthode d’essai.
