Optimising Audio
Complete Acoustic Treatment System treats resonance, reverberation and reflection as one coordinated system, with one engineered panel for each. It is built for small room acoustics, which is a technical domain rather than a size: critical listening spaces from a domestic room up to boutique commercial scale. 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 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.
Which of the three a room has is the first thing to establish, and the knowledge base is where that is worked through. Everything in it is public, without registration, including the full test report.
How a project runs
The room is modelled across all three problems, and which of the three it actually has, and in what proportion, comes out of that rather than being guessed at first. The output is a report and a treatment layout: panels placed against modelled behaviour, not by eye.
The layout is built to. The panels are designed to go in with ordinary site skills, and the relative positions are what perform, so a run is set out from the drawing rather than adjusted panel by panel.
Once the room is built, its performance is 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.
The marine sheet carries bonded data rather than a separate marine test. The marine panel is hand-made to the same geometry as the standard reference panel, and absorption is not driven by that geometry, so the bonded figures are representative. These files are the authoritative published figures.
