Model of application: meeting room
Location analysis:
Those kind of areas are useful for a reserved space where the quality of conver-
sation is the main goal. A space for interaction with digital system as well as
persons. A creative space.
Solution:
Focus the light on the desk surface, create a more snug space, juiced up by
chromatics and material interactions between textile and metallic parts.
The “dome effect” guarantee less sound dispersion and a better effective
communication.

Before
Time of reverberation* 0,9 s
After
(+ 2 Farel)
Time of reverberation 0,82 s
Decrease of reverberation
about 15%**
* 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.
