Acoustics. Determination of sound insulation performances of enclosures - Measurements in situ (for acceptance and verification purposes) Ingestion-build-46800 procedure B is better for1 Scope This part of ISO 11546 specifies in situ methods for the determination of the sound insulation performance (insertion loss) of machine enclosures. It applies to a total enclosure only and not to the individual panels from which the enclosure is made. NOTES 1 Sound insulation for enclosure panels such as wall elements, doors, windows, silencers, etc. should be measured in accordance with other relevant standards. 2 Related standards concern
