Room acoustics and technical noise protection

Schallisolierte Decke

Airborne noise insulation in buildings and optimized room acoustics

Bilz acoustic elements made from sound absorbing foam enable optimized room acoustics and airborne noise insulation in office and industrial buildings, laboratories and test cells. Our high-quality solutions for absorbing noise energy are distinguished by maximum noise insulation and minimisation of the associated sound pressure levels and the resulting resonance period.

Sound absorption

When a sound wave strikes a body it is partially absorbed and partially reflected depending on the hardness and porosity of the material. The ratio between the occurring and absorbed sound energy is therefore the sound absorption coefficient, which usually lies between 0 (complete reflection) and 1 (complete absorption).
The sound absorption EA therefore indicates the process of reducing sound energy Eo in particular (but not necessarily) by conversion into heat. The distinction from dissipation ED is that this exclusively refers to the conversion into energy other than sound, in particular heat.

Please note:

Bilz acoustic elements are available in various versions to match individual requirements, e.g.:

  • wall elements
  • ceiling sails
  • enclosures

etc.

Our delivery range also includes impact resistant, non-flammable (material class A2 according to DIN 4102) to suit the particular application.

The material can also be colour dyed or covered with printable fabric on request.
