Standard Cancelled

Acoustics - Laboratory measurement of the flanking transmission of airborne and impact sound between adjoining rooms - Part 2 : application to light elements when the junction has a small influence

ISO 10848-2:2006 applies to light elements such as suspended ceilings, access floors, light uninterrupted façades or floating floors. The transmission from one room to another can be simultaneous through the test element and via the plenum, if any. With measurements according to ISO 10848-2:2006, the total sound transmission is measured, and it is not possible to separate the two kinds of transmission.
