Sound insulation of structures

The usual structures used for construction are single or double leaf sound technically. The typical examples of single structure are concrete partition walls, massive floors and hollow-core slabs. The sound insulation of these structures is based on their mass. Double structures are usually made of lighter materials. An example of double structure would be double framed partition wall coated with construction panels . Also a floor with floating floor on it counts as a double structure sound technically speaking.

A falling object or foot steps are the impulses which make the sound in impact sound insulation. Thus insulation is mostly dependent of damping the shock made by the object with elastic coating or floating floor structures.

To some point the insulation of structures can be calculated, though the most exact method is a measurement. The sound insulation capabilities of several different structures is known from the earlier measurements. It is possible to evaluate factors affecting sound insulation or even the sound insulation of spesific structures by studying the measurement archive of the company.

The common progress when evaluating the sound insulation of structures has the following options. One is to give a statement of the architect?s or structural designer?s suggestion. Another one is trying to figure out the structure separating the partitions by their meaning of use.

The sound insulation capabilities of a structure are not only dependent on the separating structure but also on the structure by the side. Therefore it has to be taken into account that all the surrounding structures are good enough for insulation and so called flanking will not happen. Flanking can be prevented by paying attention to the junction.
