Abstract
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.

Bläsi (2002) Bauphysik, p. 206; Lutz et al. (2002), p. 12. The sound-insulation index approximately equals the difference between the measured sound levels on both sides of the sound-absorbing component when the influence of the component area and the receiving room is corrected. This is necessary because the sound-insulation index is a characteristic value of a component and is independent of its area and the sound absorption in the receiving room.

The CPD, Annex I “Basic requirements for construction works”, paragraph 5, states: “The construction works must be designed and constructed in such a way that the sound perceived by the occupants or by persons in the vicinity is kept at a level which is not hazardous to health and at which satisfactory night-time rest, leisure and working conditions are ensured” (quoted in DIN 4109-1, p. 4).
