Optimising Audio
C-ATS treats resonance, reverberation and reflection as one coordinated system, with one engineered panel for each. Every panel's absorption is measured independently to BS EN ISO 354, so a specification is built on test data rather than description.
Start a projectThe three Rs of acoustics
Resonance
At low frequencies a room resonates, so bass is strong at some seats and absent at others. The Resonance Control Panel is corner loaded, placed where modal pressure is highest, so a 43 mm panel does work that would otherwise need far greater depth. Away from a corner it is a much weaker device, and placement is not forgiving.
Reverberation
Reverberation is how long sound lingers. The target is not simply less of it, but the right decay time and the same decay on every axis. The panel is a broadband foam absorber working above roughly 200 Hz, 50 mm deep, supplied with a pre-applied adhesive backing.
Reflection
Early reflections arrive just after the direct sound and smear imaging and clarity. The Reflection Control Panel scatters that energy off axis at first reflection points. It is 3 mm injection-moulded ABS, 50 mm deep, with four countersunk fixing points.
How a project runs
Start from a designed reference room. Each layout shows a panel package and where it goes for a room of that size, so the shape of the answer is visible before a design is commissioned.
The design service models the room and returns a report and a treatment layout. It is part of the system rather than an addition to it: panels are placed against modelled behaviour, not by eye.
Once the room is built, its performance can be measured on site, so the targets the design set can be shown to have been met.
Measured performance
The values are deliberately low, because the panel scatters reflected energy rather than absorbing it. The two series are the two install types, not two versions of one figure. Bonding damps the panel, so it absorbs less and behaves as the design assumed; fixing it with screws alone leaves it free to resonate and adds absorption the design did not allow for.
