Project Details


Calculations of the acoustic behavior of building structures are based amongst others in the international standard series EN ISO 12354. In these standards, a model is used, which can be preferably applied to massive, homogeneous constructions. The joints of the structures are specified by the so-called “flanking sound reduction index”. The usage of this model for solid wood constructions - for example laminated timber - is still unsatisfactory in regard to the behavior of the joints, on one hand because the definition of the boundary conditions. On the other hand, a lack of suitable models avoids to describe the main transfer paths for specific solid wood construction systems. To solve this problem it is proposed to develop appropriate mathematical models and to identify the - in practice - most important parameters. Based on that, it is planned to perform measurements on models in the laboratory to investigate the complex interactions of currently undefined boundary conditions of joints.
