Structure-borne sound insulation

Structure-borne sound is created by the transfer of airborne sound to sound-reflecting surfaces or when two solid bodies meet. Wherever flow noises, for example in water or heating pipes, or machine vibrations are passed on, effective structure-borne sound insulation is of great importance. Here, cushioning insulating materials of various types are interposed to limit the propagation of airborne and structure-borne sound.

Good structure-borne sound insulation attempts to prevent the body from vibrating in advance. This is achieved, for example, with the help of composite foams or insulation boards. The required properties of these materials depend, among other things, on the frequency and volume of the vibrations.
