Acoustics - Determination of sound insulation performance of cabins - Laboratory and in situ measurements (ISO 11957:1996)
Describes a laboratory method and in situ methods for the determination of the sound insulation performance of sound-protecting cabins. Applicable to sound-protecting cabins with a leak ratio smaller than 2 %.
Akustik - Messung der Schalldämmung von Schallschutzkabinen - Messungen im Labor und im Einsatzfall (ISO 11957:1996)
Diese Internationale Norm legt Verfahren zur Messung der Schalldämmung von Schallschutzkabinen im Labor (Abschnitt 6) und im Einsatzfall (Abschnitt 7) fest. Die Schalldämmung ist die von der Kabine bewirkte Minderung des Schalldruck- oder Schalleistungspegels. Die Verfahren sind auf Schallschutzkabinen mit geringem Öffnungsanteil ( 2 %) anwendbar.
Diese Internationale Norm gilt nur für eine vollständige Schallschutzkabine und nicht für die einzelnen Bauteile, aus denen sie hergestellt wurde.
ANMERKUNG 1 Die Schalldämmungen für Kabinenteile, wie z. B. Wandelemente, Türen, Fenster, Schalldämpfer, sollten nach anderen diesbezüglichen Normen gemessen werden.
Die Anforderungen an die Messumgebung im Labor basieren auf denjenigen, die in ISO 3741 festgelegt sind.
Acoustique - Détermination des performances d'isolation acoustique des cabines - Mesurages en laboratoire et in situ (ISO 11957:1996)
La présente Norme internationale décrit une méthode de laboratoire (article 6) et des méthodes in situ (article 7) pour la détermination des performances d'isolation acoustique des cabines de protection phonique. La performance d'isolation acoustique est la réduction du niveau de pression acoustique ou du niveau de puissance acoustique occasionné par la cabine. Les méthodes sont applicables à des cabines à faible taux de fuite (θ < 2 %). La présente Norme internationale s'applique exclusivement à une cabine complète et non aux composants individuels qui la constituent.
NOTE 1 L'isolement acoustique des composants de la cabine, tels que les éléments de cloison, les portes, les fenêtres, les silencieux, etc., devrait être mesuré suivant les normes adéquates. Les exigences concernant l'environnement d'essai en laboratoire sont basées sur celles figurant dans l'ISO 3741.

Foreword
IS0 (the International Organization for Standardization) is a worldwide fed-
eration of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in lialison with ISO, also take part in the work. IS0 collabo-
rates closely with the International Electrotechnical Commission (IEC) on
all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are cir-
culated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 11957 was prepared by Technical Committee
ISO/lC 43, Acoustics, Subcommittee SC 1, Noise, on request from
CEN/TC 211, Acoustics.
Related standards concern noise attenuation measurements of enclosures
under laboratory conditions (IS0 11546-l) and in situ (IS0 11546-2).
Annexes A and B of this International Standard are for information only.
