Absorbers

Absorbers are a fused, layered composite made out of either foam or fibers that absorb reverberations bouncing off hard surfaces. Depending on the frequency of sound, the operating environment, and your technical requirements, we design sound absorption products that can be customized for a specific sound or purpose and are available with multiple facings for functional and aesthetic purposes.

 

 

 

 

 

  • Wide variety of foam or non-woven absorbing materials available .
  • Multiple thickness and densities are available depending on the application.
  • Available facings to both tune the absorption spectrum and to compensate for environmental conditions.
  • Materials can be supplied with or without pressure sensitive adhesive.
