Acoustics. Determination of sound insulation performances of enclosures - Measurements under laboratory conditions (for declaration purposes) has-digital The liberated cyanide is determined1 Scope This part 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. 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
