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

Now up for auction: a pallet of 62 colour-defective acoustic panels!

On these panels the sides of the slats were left without the dark colour and the black finish appears more grey.

See the photos for details. Note! Panels have plastic wrap on top.

Note! The photo shows only 8 pieces; the auction is for 62 pieces, i.e. one pallet!

62 pcs Evella VN40 black oak 2400x600 mm wood-veneer acoustic panels

Beautiful and functional acoustic decorative panels. Slat width 40 mm. Single panel dimensions 2400 x 600 mm. Includes black fixing screws for wall installation.

Evella acoustic panels are a quick and effortless way to create a modern, architectural look in a space. The panels suit modern Scandinavian style and create a seamless slatted wall surface while significantly improving room acoustics.

The backing felt of the acoustic panel is 100% recycled polyester fibre, specially developed to reduce noise and shorten reverberation. MDF slats fixed onto the felt are covered with genuine wood veneer, giving the panel a natural, attractive 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 absorbing material that takes up sound

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

Although a slatted panel does not absorb sound as effectively as a traditional absorptive panel, it often creates a more balanced and natural acoustic, especially in living spaces. The difference is noticeable in, for example, clearer conversations and reduced reverberation of loud noises such as bangs.

Natural sound environment
The panel’s natural effect comes from part of the sound reflecting off the slats and being scattered more gently. This shortens reverberation and makes the room less echoey, improving comfort for living and working. In speech, listeners need to process less reverberant sound, which helps with clarity, e.g. for those with hearing difficulties.

Tip: You can easily test the room’s reverberation by clapping your hands once in different parts of the room. In a highly reverberant space you will hear how long the echo persists.

Installation
Panels are easiest screwed directly to battens. For concrete walls a horizontal battens layout is recommended. The included black drywall screws blend into the felt; additional screws are readily available from hardware stores.

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

• Install the panel off the wall on battens so sound does not immediately reflect back through the felt but reflects at multiple interfaces

• Add mineral wool between the battens to increase absorption. Any used or worn-looking insulation is acceptable as it will be hidden

The panel can also be mounted directly over partition wall insulation without drywall, but then the effect is limited to the room’s internal acoustics. A drawback is that sound transmits more easily to adjacent rooms and the panel will not act as an effective sound barrier as a missing plasterboard would.

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