Location analysis
a pleasant workspace must guarantee a perfect balance between
correct, uniform lighting of worksurfaces and a comfortable acoustic
“situation” in which the noise produced inside the space is reduced
to a minimum level.
Solution
Pétale suspensions combine the technology of a fiberglass panel
that absorbs the sound waves reflected by the room’s surfaces
with an integrated high-performance lighting module. The result is a
comfortable lightscape and a pleasing acoustic sensation.

* Measuring reverberation time allows to calculate total sound
absorption. Reverberation time varies according to the frequency.
If reverberation time is too long, the space can have echoes and
rumbles.
** The data is always approximate: the software doesn’t take in
consideration the position of the speaker and the position of absorbent
surfaces.
