37、plies to a total enclosure only and not to the in- dividual Panels from which the enclosure is made. NOTES 1 Sound insulation for enclosure Panels such as wall el- ements, doors, windows, silencers, etc. should be measured in accordance with other relevant Standards. 2 Related Standards concern nois
38、e-attenuation measure- ments of enclosures under laboratoty conditions (ISO 11546-1) and cabins (ISO 11957). 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,
39、the Sound insulation Performance (insertion loss) of the enclos- ure is determined in terms of the reduction of Sound power level or Sound pressure level. Methods are given for measurements where the enclosure sur- rounds the actual Sound Source (machine). When these methods are not practicable, alt
40、ernative measurements tan be performed with an artificial Sound Source. Such methods are also described in this part of ISO 11546. 2 Normative references The following Standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 11546.
