Abstract: This paper describes the implementation of airborne sound insulation model in buildings based on ISO-EN: 12354 part I (2017). It comprehends the calculation procedures to evaluate the performance of the building elements, from where we can evaluate the overall performance of the buildings in terms of noise and comfort. The basic parameters that are necessary for the development of the model are based on calculations and/or on measurements in addition to the material properties of the building elements, according to the ISO standards. It focuses on to investigate the performance of the building elements in terms of sound transmission between dwellings by partitions and by flanking structures. The most important data needed are the sound reduction index for direct transmission of the different structures and the vibration level differences across junctions. A comparison between calculation and measurement for different situations is presented by considering different type of building elements and their constructions. Furthermore, based on this model, we suggest algorithm for airborne sound insulation filters for auralization of buildings as an application for the extension towards virtual reality (VR) systems.
