Acoustics. Determination of sound insulation performance of cabins. Laboratory and in situ measurements Ingestion-build-146508 Footwear refers to garments worn1 Scope This International Standard specifies a laboratory method (clause 6) and in situ methods (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 ( 2%). This International Standard is applicable to a complete cabin only and not
