Acoustics - Determination of sound insulation performances of enclosures - Part 2: Measurements in situ (for acceptance and verification purposes) (ISO 11546-2:1995); German version EN ISO 11546-2:2009
The method for the determination of the sound insulation performance of enclosures under in-situ conditions is standardised. The measurements can be carried out using either the machine to be enclosed as the sound source, or using an artifical sound source. The sound insulation is given as either sound pressure or sound power insulation. It applies to complete enclosures only (not their constituent parts).
