Pallet of colour-defective Evella acoustic panels — 62 pieces in total!, Lahti

Now on auction: 62 colour-defective acoustic panels, sold as a pallet!

On these “wasp slat” panels the sides of the slats have been left without the dark colour and

the black finish appears more grey.

See the photos for details. Note! There is cling film on top of the panels.

Note! The photo shows only 8 panels — the auction is for 62 panels (one pallet)!

62 pieces of Evella VN40 Black Oak 2400 x 600 mm wood-veneer acoustic panels

A beautiful and functional acoustic interior panel. Slat width 40 mm. Individual panel dimensions 2400 x 600 mm. Includes black installation screws for wall mounting.

Evella acoustic interior panels are a quick and easy way to create a modern, architectural look. The panels suit modern Scandinavian interiors and create a seamless slatted wall surface while noticeably improving room acoustics.

The panel’s backing felt is 100% recycled polyester fibre, specially developed to reduce noise levels and remove room reverberation. MDF slats fixed to the backing are covered with real wood veneer, giving the panel a natural, elegant finish. Installation can be done with the supplied screws or with adhesive purchased separately.

How it works
A slatted acoustic panel reduces sound in two ways:

• The felt acts as an absorptive material that soaks up sound

• The slats and their gaps scatter sound by diffraction, sending it in different directions

Although slatted panels do not absorb sound as effectively as traditional insulation boards, they often create a more balanced and natural acoustic, especially in living areas. The difference can be noticed in clearer conversation or reduced echo from sharp noises such as bangs.

Natural sound environment
The panel’s natural effect comes from some sound being reflected by the slats and more softly scattered. This shortens reverberation and makes the room less echoey, improving comfort for living and working. Particularly for speech, listeners need to process less echoed sound, which also helps with clearer hearing, e.g. for those with hearing difficulties.

Tip! You can easily test a room’s reverberation by clapping your hands once in different parts of the room. In a very echoey space you will hear how long the reverberation lingers.

Installation
Panels are easiest to screw directly to battens. For concrete walls, horizontal battens are recommended. The supplied black drywall screws blend into the felt, and additional screws are readily available from any DIY store.

If you want to extend the effective absorption to slightly lower frequencies — for example for music listening — you can:

• Install the panel detached from the wall onto battens so sound does not immediately reflect back after passing through the felt and instead reflects from multiple interfaces

• Add mineral wool between the battens to enhance absorption. The wool or an acoustic panel used between can be second‑hand and worn on the surface, since it will be hidden

The panel can also be installed directly over partition-wall insulation without drywall, but then the effect is limited to the room where it is installed. The downside is that sound may travel more easily to the adjacent room, and the panel will not act as effectively as sound insulation as a missing drywall would.

Practicality
Evella panels offer an easy way to finish large surfaces without demolition or plastering work. They are suitable for walls and ceilings, and can be installed quickly.
