Abstract Part 1 of ISO 11546 specifies laboratory methods for the determination of the sound insulation performance (insertion loss) of small machine enclosures. It applies to a total enclosure only and not to the individual panels from which the enclosure is made. The measurement methods specified are based on International Standards in the series ISO 3640, ISO 9614 and ISO 11200. Depending on the method chosen, the sound insulation performance of the enclosure is determined in terms of the reduction of sound power level or sound pressure level. Part 2 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. The measurement methods specified in this part of ISO 11546 are based on International Standards in the series ISO 3740, ISO 9614 and ISO 11200. Depending on the method chosen, the sound insulation performance of the enclosure is determined in terms of the reduction of sound power level or sound pressure level.
