HIGH-QUALITY ACOUSTIC ABSORPTION

Material made of open-cell polyurethane with a smooth repellent coating that eliminates annoying sound reflections.

SOUND ABSORPTION

Sound-absorbing materials reduce sound reflections in a fully or partially enclosed space. This reduces the sound level within this room. Of course, the sound level outside this room (e.g. a machine room) will also be lower. Sound absorption is achieved by allowing sound waves to penetrate into a porous material. The vibration energy is converted into a non-measurable amount of heat. In addition to sound, harmful substances such as vapors and liquids can often penetrate the foam. To prevent this, a covering layer is applied, which of course must be able to allow sound to pass through. The sound absorption of acoustic materials increases with greater material thickness, especially for bass. The amount of sound that is absorbed is expressed in a so-called sound absorption coefficient.
