| Organization: | NEN |
| Publication Date: | 1 September 1997 |
| Status: | inactive |
| ICS Code (Acoustics in building. Sound insulation): | 91.120.20 |
scope:
This standard shows how to represent the sound insulation of building elements, measured in the laboratory, in a single number. This standard treats two quantities with which the insulation of airborne sound can be described in a single number: Ilu, the laboratory insulation index for all building elements and RA, the A-weighted airborne sound insulation for specific facade elements. With respect to impact sound insulation this standard treats a single quantity: Ico,lab, the laboratory insulation index for impact sound. The standard applies to building elements and constructions of which the sound insulation has been determined in the laboratory by measurements in accordance with enquiry NEN 1070:1997.
