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-protection 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 (θ≤2%) . This International Standard is applicable to a complete cabin only and not to the individual components from which it is made.
