适用范围：The document specifies methods for the determination of the sound insulation performance of sound-insulating cabins by measurements under laboratory or in-situ conditions. The sound insulation is the reduction in sound power level or sound pressure level effected by the cabin. The methods can be applied to closed cabins or cabins with little leakage. Only complete cabins (as opposed to building elements) can be measured according to the document. The requirements for the measurement environment are based upon those of ISO 3741.
