Effective masking at all times
Our active adjustment system identifies variations in
ambient noise in real time, from signals supplied by
sound level sensors installed in the ceiling of the work
space. And, thanks to an advanced signal-processing
procedure, it automatically adjusts the masking
volume depending on the intensity of conversational
noise and other noise distractions.
Maintenance of acoustic comfort
with gradual adjustment
We know that to be acceptable in a work environment,
sound masking must be as undetectable as possible.
This is why the active system adjusts to ambient noise
variations gradually. Modifications to sound masking
volume are, quite simply, imperceptible.

Superior masking quality and acoustic comfort
An office space is a dynamic site in which ambient noise and the volume of sound distractions
vary a great deal depending on the schedule and activities underway. In order to be optimal,
sound masking must adapt to changes: It must increase during very active periods, and
become more discreet when the area is quieter. Now, SmartSMS makes this possible!
