How grooved acoustic panel absorb sound ?

As well as the grooves in the face , cut-outs to the rear or the centre meet in grooves , creating perforations .

These perforations , combined with a cavity behind the panel create resonance , due to the air in the cavity which acts like string .

In combination with damping , typically provided by a layer of mineral fibre in the cavity , to reduce sound energy.

This is known as a Helmholtz absorber.

Changing the perforation pattern (in this case by selecting the width between the slits) alters the acoustic performance .

Differences in the cavity depth and absorbent material in the void also have consequences.

Sound absorption data in NRC0.85

For sound absorbing the measurements were carried out according to BS EN ISO354:2003 "Acoustics measurement of sound absorption in a reverberation room" .

Fireproofing performance result in B-s1,d0

Based on EN13501-1:2018 Fire classification of construction products and building elements - part 1 : Classification using data from reaction to fire tests of Smoke production in s1 and Flaming droplets in d0 .

Professional packaging , ultimate protection , custom wooden cases tailor made 

We provide customized wooden boxes for all the exported products , ensuring the goods remain stable and secure during long-distance transit .

FAQ

Q: Can the panels be used on ceilings as well as walls?
A: Absolutely. Our slotted acoustic panels are suitable for both wall and ceiling applications. For ceilings, we recommend using appropriate fixing systems to ensure secure installation and safety.

Q: How do I clean and maintain the panels?
A: Maintenance is minimal. Regular dusting with a soft cloth or brush is usually sufficient. For deeper cleaning, use a slightly damp cloth and wipe gently. Avoid using excessive water or harsh chemical cleaners, as they may damage the wood surface.

Q: How do I choose between slotted panels and perforated panels?
A: Slotted panels offer a more linear, modern aesthetic and are excellent for mid-frequency absorption. Perforated panels have a dotted pattern and are typically better for high-frequency absorption. Your choice depends on your acoustic goals and design preference. We can advise you based on your specific room acoustics.
