Why 45dB?
Accurate calibration
Automatic narrowband calibration tunes the masking sound to the acoustic response of each space.
Adaptive masking
Optional sensors adjust masking levels as workplace activity changes, within the limits set for each zone.
Networked control
Manage zones and system settings from a central interface, with remote access where configured.
Less distracting speech. More room to focus.
In a very quiet office, conversations carry further and are easier to understand. Sound masking adds a carefully tuned background sound that makes distant speech less distinct.
Combined with sound absorption and isolation, it helps people collaborate nearby while others concentrate.

From your floor plan to a commissioned system
Design and specification
Send us your floor plans and reflected ceiling plans. We develop the speaker layout and zoning around your acoustic brief.
Coordination and installation
We work with architects, acoustic consultants and builders to coordinate the system with ceiling types, services and the construction programme.
Calibration and support
We commission and calibrate the system for the finished space, with ongoing support as your workplace changes.
For the love of sound
Why shouldn’t the places we work in be as comfortable on our ears as they are beautiful to our eyes?
That question drives our work. We bring sound masking into the design conversation early, helping create spaces for both focused work and collaboration.
