Possibilities to improve the modelling in EN 12354 for lightweight elements
conference paper
The standard EN 12354 gives prediction models for the airborne and impact sound transmission between rooms in buildings. For buildings with mainly heavy, monolithic structures the standard has proven to be quite useful. However, in case of lightweight building elements the standard only gives global indications about the appropriate modelling. In principle various possibilities exist, each with their own advantages and restrictions. It is important to realize that the way the transmission is modelled has consequences for the kind of input data needed and hence for the quantities determined by the flanking measurement methods as described in ISO 10848. Questions as how to measure the vibration reduction index (K</field>ij), when and how to the apply the flanking level difference (A</field>nf or L</field>nf) and even how to measure or adjust the sound reduction index (R) can only be answered in the context of their use in the modelling of the sound transmission. A future revision of the standard will have to deal with these questions in more detail. Based on ongoing research and reported research over the past years on the subject of lightweight building elements, some possibilities are presented.
