Structure-borne sound damping for an optimal sound level

Extra weight is added to a product to reduce vibrations and achieve a damping effect.

Extra weight is added to a product to reduce vibrations and achieve a damping effect.
Materials are available with densities from 1.2 kg/m² to 10 kg/m².
The materials are also used as high-density layers to make the noise to be reflected against the surface. For example, cladding the walls of a cabinet with high density material causes the sound to be retained in the cabinet. Sandwich constructions of different materials is often used to achieve an optimal sound level.
