Acoustics - Determination of sound insulation performance of cabins - Laboratory and in situ measurements (ISO 11957:1996)

This International Standard specifies a laboratory method (clause 6) and in situ method (clause 7) for the determination of the sound insulation performance of sound-protecting cabins. The sound insulation performance is the reduction in sound pressure level or sound power level afforded by the cabin. The methods are applicable to cabins with a small leak ratio (q ? 2%).  This International Standard is applicable to a complete cabin only and not to the individual components from which it is made.  NOTE 1: Sound insulations for cabin components such as wall elements, doors, windows, silencers, etc. should be measured according to other relevant standards.  Requirements for the test environment in the laboratory are based on those given in ISO 3741.

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 (teta <= 2%) anwendbar.
