Sound absorption

Sound absorption is the ability of a surface to absorb sound, minimizing sound reflection in the room.

Reflected sounds create undesired and uncomfortable reverberations throughout the area and will ultimately increase the perceived sound level.

vektron suspended ceilings are an important factor in reducing these undesired reflections through the use of sound absorbing materials, combined with the perforations in the ceiling allowing the sound to pass through.

Details

The sound absorption coefficient αW is the fraction of the total sound that is absorbed by the suspended ceiling. The remaining unabsorbed fraction is reflected back into the room.

The sound absorption coefficient has a value between 0,0 (no absorption - all the sound is reflected) and 1,0 (complete absorption - equivalent to an open window).

The absorption factor is measured according EN20354:2003 and EN11654:1997

vektron ceilings are available in different perforations equipped with an acoustic fleece. Shrink-wrapped wool inlays are available as an option to further improve the acoustic performance.
The absorption factor for different combinations of perforations and acoustic options ranges from 0,45 (standard perforation, 100mm non-perfo border, acoustic fleece) to 1,00 (standard perforation, full-perfo field, sealed mineral wool inlay)
