ALPHAcoustic – AB.Sine are sinusoidal sound absorbing ceiling baffles. They are a variant of ALPHAcoustic – AB.Ortho.
These baffles are suspended vertically from the ceiling in parallel lines, as defined by the respective acoustic study. They offer a different, elegant aesthetic in the space.
Standard dimensions: 120x40cm and 180x40cm
Thickness: 30-50-80mm
(different shapes, dimensions and thickness can be made upon request)
Due to their two very effective sound-absorbing sides, these elements can achieve high sound absorption. They also reduce annoying multiple noise reflections to improve interior acoustics and reduce echo. They create a better acoustic environment, without disturbing the operation of the air conditioning and the lighting system.
The sound absorbing panels ALPHAcoustic – AB have been measured according to ISO 354:2003. For panels with dimensions of 1200x600x80 mm, suspended at distances of 600 mm between them, the sound absorption coefficient is shown in the following table (where αN is the equivalent sound absorbing surface per object).
| Sample type: ALPHAcoustic – AB 1200 mm x 600 mm x 80 mm |
Frequency (Hz) | |||||
|---|---|---|---|---|---|---|
| 125 | 250 | 500 | 1000 | 2000 | 4000 | |
| Sound Absorption Coefficient (αN) | 0.2 | 0.43 | 0.98 | 1.4 | 1.4 | 1.3 |
