Sound Protection

The main focus of constructional design in building in acoustic terms is the sound-insulation of interior spaces from external noise sources, be it located outside the building or in neighboring interior spaces, so that no intolerable perturbances are to be expected. In constructional terms, both the material composition and the particular layering of an envelope component are crucial to its acoustic behaviour. Sound can be either insulated either by sufficient mass or alternatively by a system of vibrating parallel leaves as are to be found in multileaf or multi-layer components. Special attention must be given in the latter case to parameters like the bending stiffness and the areal mass of the leaves, as well as their separation and the resilience of their mutual connection.
