Soft dB Sound Masking Systems

A 340 narrow band equalization (instead of the usual 20 1/3 octave bands) ensures the production of a uniquely smooth, regular and comfortable sound masking, irrespective of the acoustical characteristics of the work space (Patent US 7460675 B2). Continuously adjusts the masking sound level based on ambient noise measurement. In a busy work area, the masking sound increases. It decreases when the work area quiets down (Patent US 8116 461 B2).

E ffe c t iv e M a s k in g a t A ll T im e s Our adaptive adjustment system (US 8116461 B2) 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 technology, it automatically adjusts the masking volume depending on the intensity of conversational noise and other noise distractions. Adaptive sound level adjustment 65 The active volume control system ensures unparalleled acoustic comfort and effective sound masking throughout the day, however busy or quiet the...

G r e a t e r C o n fid e n t ia lit y in A ll E n v ir o n m e n t s O p e n - P la n O ffic e s Sound is easily transmitted throughout open-plan offices, given that there are no doors or walls to block propagation. Conversations are clearly perceived, which disturbs colleagues both nearby and further away. Sound masking raises the acoustic comfort level of open-plan offices by reducing the distraction radius. Hence, people are significantly less distracted by conversations that take place within a radius of 40 to 15 feet from where the sound masking loudspeaker is located. With masking...
