适用范围：This document describes calculation models designed to estimate the airborne sound insulation between rooms inbuildings, primarily using measured data which characterize direct or indirect flanking transmission by theparticipating building elements and theoretically derived methods of sound propagation in structural elements.A detailed model is described for calculation in frequency bands ; the single number rating can be determined fromthe calculation results. A simplified model with a restricted field of application is deduced from this, calculatingdirectly the single number rating, using the single number ratings of the elements.This document describes the principles of the calculation scheme, lists the relevant quantities and defines itsapplications and restrictions. It is intended for acoustical experts and provides the framework for the developmentof application documents and tools for other users in the field of building construction, taking into account localcircumstances.The calculation models described use the most general approach for engineering purposes, with a clear link tomeasurable quantities that specify the performance of building elements. The known limitations of these calculationmodels are described in this document. Users should, however, be aware that other calculation models also exist,each with their own applicability and restrictions.The models are based on experience with predictions for dwellings ; they could also be used for other types ofbuildings provided the construction systems and dimensions of elements are not too different from those indwellings.
