acoustics
Ceilings have a considerable influence on the
acoustic performance of a space and should be
designed in such a way as to address the aural
demands of the occupants within.
Sound absorption is the ability of a surface to
absorb sound, to minimize sound reflection in
the room. Reflected sounds create undesired
and uncomfortable reverberations throughout
the area and will ultimately increase the
perceived sound level.
� 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.
The sound absorption coefficient aw 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.
