Pallet of Evella acoustic panels with colour defects — 62 pieces in total!, Lahti

Now listed: 62 colour-defective acoustic panels — one pallet!

On these panels the slat sides have been left without the dark finish and

the black colouring appears more like grey.

See the photos for details. Note: panels are covered with plastic film.

Note: the photo shows only 8 pieces; the lot contains 62 pieces (one pallet)!

62 pieces Evella VN40 black oak 2400 x 600 mm wood-veneer acoustic panels

Attractive and functional acoustic interior panels. Slat width 40 mm. Single panel size 2400 x 600 mm. Includes black mounting screws for wall installation.

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

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

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

• The backing felt acts as an absorbing material that soaks up sound

• The slats and their gaps scatter sound by diffraction, i.e. disperse it in different directions

While a slatted panel does not absorb sound as effectively as a traditional insulation panel, it often creates a more balanced and natural acoustic, especially in living spaces. The difference can be noticed in speech clarity or reduced reverberation of loud noises such as bangs.

Natural sound environment
The panel’s natural effect comes from some sound being reflected by the slats and scattered more softly. This shortens reverberation and makes the space less echoey, improving comfort in homes and workspaces. In speech, listeners have less reverberation to process, which can help with clarity, for example for people with hearing difficulties.

Tip! You can easily test room reverberation by clapping your hands once in different parts of the room. In a highly reverberant space you will hear how long the sound 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 hardware stores.

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

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

• Add mineral wool in the batten cavities to increase absorption. The wool or an extra acoustic panel placed behind can even be used/appear worn since it will be hidden

The panel can also be installed directly over partition-wall insulation without plasterboard, but this limits the effect to the room’s internal acoustics. A downside is that sound transmits more easily to adjacent rooms and the panel will not perform as well as a sound barrier compared with a missing plasterboard layer.

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