This part of ISO 11546 specifies laboratory methods for the determination of the Sound insulation performance (insertion loss) of small machine enclosures. lt 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 (see table 1). Depending on the method Chosen, the Sound insulation Performance (insertion loss) of the enclosure is determined in terms of the reduction of Sound power level or Sound pressure level. Methods are given for measurements where the enclosure surrounds the actual Sound Source (machine). Where these methods are not practicable, alternative measurements tan be performed using a reciprocity method (see definition 3.11 and subclause 7.2) or an artificial Sound Source.
