简介:Diese Internationale Norm legt Verfahren für die Bestimmung der Schallleistungs- oder Schallenergiepegel einer Ger?uschquelle aus Schalldruckpegeln fest, die auf einer Fl?che gemessen werden, die die Ger?uschquelle (eine Maschine oder ein Ger?t) umschlie?t (Hüllfl?che), wobei sich die Ger?uschquelle in einer Messumgebung befindet, für die Anforderungen angegeben werden. Der von der Ger?uschquelle abgestrahlte A-bewertete Schallleistungspegel (oder Schallenergiepegel bei Impulsen oder anderen Ger?uschen kurzer Dauer) wird aus den gemessenen Schalldruckpegeln berechnet. ANMERKUNG Unterschiedliche Messfl?chenformen k?nnen zu unterschiedlichen Sch?tzwerten des Schallleistungspegels der betrachteten Ger?uschquelle führen. Daher sind geeignet formulierten Ger?uschmessnorm (siehe ISO 12001) genaue Angaben zur Auswahl der Messfl?che enthalten. Die in dieser Internationalen Norm festgelegten Verfahren sind für alle in ISO 12001 definierten Arten von Ger?uschen geeignet (gleichf?rmige, ungleichf?rmige, schwankende, Einzel-Schallimpulse usw.). Diese Internationale Norm gilt für Ger?uschquellen aller Art und Gr??e (z. B. eine station?re oder sich langsam fortbewegende Anlage, technische Einrichtung, Maschine, Komponente oder Baugruppe), solange die Messbedingungen erfüllt werden k?nnen. ANMERKUNG Die Messbedingungen nach dieser Internationalen Norm k?nnen in der Praxis bei sehr hohen oder sehr langen Ger?uschquellen wie Schornsteinen, Kan?len, F?rderb?ndern und Industrieanlagen mit vielen Ger?uschquellen zu Schwierigkeiten führen. In solchen F?llen k?nnen in einer Ger?uschmessnorm für diese speziellen Quellen alternative Verfahren angegeben sein. Als Umgebung zur Durchführung von Messungen nach dieser Internationalen Norm eignet sich ein Ort in einem geschlossenen Raum oder im Freien, der eine oder mehrere Schall reflektierende Ebenen aufweist, auf der oder in deren N?he die zu untersuchende Ger?uschquelle angeordnet wird. Es werden Angaben zur Unsicherheit der nach dieser Internationalen Norm ermittelten A-bewerteten Schallleistungs- und Schallenergiepegel gemacht. Die Unsicherheit entspricht der Genauigkeitsklasse 3 nach ISO 12001:1996.
