Location analysis
the quality of a restaurant is a combination of different factors: quality
of food, service and environment and a good quality of speech combined
with acoustic comfort.
Solution
the Silenzio suspensions are the perfect solution because they are
simple shapes which enrich the spaces thanks to the high quality of the
textiles; they diffuse a comfortable light and provide high levels of
acoustic absorption.
Room data
L = 15 m
W= 7 m
H= 5,5 m
Different height from 2,5 mt to 2,9 mt AFF
Lighting source used
LED module 41W
Fixtures installation
5 x Silenzio Ø 90 cm
9 x Silenzio Ø 120 cm
Illuminance average
Table (min) 180 lx
Table (max) 452 lx
Before
time of reverberation* 3,16 s
After
(with Silenzio) time of reverberation 1,55 s
Decrease of reverberation: about 51%**
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 considera-
tion the position of the speaker and the position of absorbent surfaces.
