Structure-borne sound insulation
Frequently asked questions (FAQ)
Generally speaking, structure-borne sound is sound that propagates in solid bodies such as steel, concrete, etc. through vibration.
Structure-borne sound is sound that propagates in a solid body. When sound is transmitted to a solid body, the latter is set into vibration by the sound transmission. Thereby the sound propagates e.g. over thin-walled metal sheets or over the masonry.
The well-known effects of structure-borne noise result in the unavoidable need to create effective vibration insulation. A technologically relatively simple type of structure-borne sound insulation is achieved by installing an intermediate layer as close as possible to the source of interference, which interrupts the path of the sound vibrations. Motors, for example, are placed on specially designed vibration insulation bodies, thereby making them a vibration system that is almost independent of the environment or support. The same applies to building floors which are periodically subjected to powerful horizontal and vertical impulses at the same time, which are then freed from vibrations both horizontally and vertically by insulation.

The basic rule when using bituminous or plastic heavy foils as anti-drumming when bonding sheeting is: The sheet thickness x 2 gives the thickness of the anti-drumming foil, 2/3 of which is applied to the surface.
Structure-borne sound insulation - anti-drumming, the transmission of sound in solid bodies. While the construction materials of machines and buildings such as cast iron, steel and concrete are good conductors of sound and are therefore described as sound-reflecting in analogy to the material consistency, rubber, on the other hand, conducts sound poorly and is very well suited as a softer material for structure-borne sound insulation. The damping effect for structure-borne sound waves is due to their partial reflection at the interface of the materials and only a part of them penetrates the intermediate layer.
