That depends on the size of the room and the desired effect.
As a rule of thumb:

• 20–30% of wall space → noticeable improvement
• more surface area → stronger effect

For living spaces, just a few panels are often enough to create a focal point.

Akustikpaneele verbessern in erster Linie die Raumakustik innerhalb des Raumes und reduzieren Hall sowie Echo. Gegen laute Nachbarn oder starken Trittschall helfen sie nur begrenzt.

Für eine spürbare Schalldämmung zwischen Räumen sind spezielle Schallschutzsysteme erforderlich. Akustikpaneele sorgen jedoch dafür, dass Räume insgesamt ruhiger wirken und Geräusche weniger „hart“ wahrgenommen werden.

Acoustic panels are easy to install - either:

• using installation adhesive (quick & clean)
• or with screws (especially sturdy)

Installation is easy, even without any DIY experience.

Both options are possible:

• Gluing: fast, clean, ideal for walls
• Screwing: maximum stability, ideal for ceilings

For ceilings, we recommend a combination of gluing and screwing.

Yes, acoustic panels can be custom-cut.
You can:

• trim them yourself using standard tools
• or use our cutting service - for a perfect fit with no hassle

In vielen Fällen ja. Wichtig ist, dass die Tapete sauber haftet und der Untergrund tragfähig ist. Locker sitzende oder empfindliche Tapeten sollten vorher entfernt werden.

Für eine dauerhaft sichere Befestigung empfehlen wir die Montage auf festen Untergründen wie Putz, Beton, Holz oder Rigips.

Yes, acoustic panels can also be mounted on the ceiling, where they are particularly effective at improving room acoustics. It is important to secure them properly - ideally with screws or a combination of screws and mounting adhesive.

Yes, they are ideal for bedrooms.
They provide:

• less reverberation
• a calmer atmosphere
• a more pleasant sense of space

Absolutely. Especially in offices, conference rooms, or studios, acoustic panels reduce disruptive noise and significantly improve speech intelligibility. 

Yes - especially when installed with adhesive, many panels can be removed without leaving any residue (depending on the surface).

Acoustic panels are available in various sizes, e.g.:

• 2600 x 400 mm
• 2400 x 600 mm
• 2600 x 600 mm
• 3000 x 400 mm
• smaller sizes such as 800 x 400 mm or 400 x 400 mm

This allows them to be flexibly adapted to any wall.

Both.
Acoustic panels combine:

• functional sound insulation
• with modern wall design

So they are both a design element and an acoustic solution in one.

Several factors play an important role when buying acoustic panels:

• Finish of the slats
  High-quality panels feature neatly finished and fully wrapped slats for a uniform overall appearance.
• Material Quality
  A sturdy backing board and dense acoustic felt ensure better durability and noticeable sound absorption.
• Installation & Customization
  Good panels are easy to install and can be cut to size or customized as needed.
• Sizes & Variants
  Different dimensions and finishes allow for flexible design in any room.

👉 High-quality acoustic panels thus combine functionality, easy installation, and modern design in a single product.

Coated slats are coated all around - not just on the front.

Advantages:

• No visible cut edges
• Higher-quality appearance
• Uniform overall appearance

This makes a huge visual difference.

Akustikpaneele können auf vielen Untergründen montiert werden, darunter:

• Beton
• Putz
• Rigips
• Holz
• Fliesen

Wichtig ist ein sauberer, trockener und tragfähiger Untergrund. Bei empfindlichen oder unebenen Flächen empfehlen wir eine Verschraubung.

Ja, Akustikpaneele können sowohl vertikal als auch horizontal montiert werden. Die horizontale Montage wird häufig für moderne Wandgestaltungen oder besondere Designkonzepte verwendet.

Die akustische Wirkung bleibt dabei grundsätzlich erhalten.

Akustikpaneele sind pflegeleicht und lassen sich einfach reinigen. Staub kann mit einem Staubwedel, Mikrofasertuch oder Staubsauger mit Bürstenaufsatz entfernt werden.

Leichte Verschmutzungen lassen sich meist mit einem leicht feuchten Tuch reinigen.

Hochwertige Akustikpaneele erkennt man unter anderem an:

• vollständig ummantelten Lamellen
• sauberer Verarbeitung
• stabilem MDF-Träger
• dichtem Akustikfilz
• präzisen Abständen der Lamellen

Qualitativ hochwertige Paneele wirken nicht nur optisch edler, sondern bieten meist auch eine bessere Stabilität und Schallabsorption.

Günstige Akustikpaneele besitzen oft einfache, nur vorne beschichtete Lamellen und dünneren Filz. Dadurch entstehen häufig sichtbare Schnittkanten und eine weniger hochwertige Optik.

Hochwertige Akustikpaneele bieten dagegen:

• rundum ummantelte Lamellen
• stabileren Aufbau
• bessere Verarbeitung
• hochwertigere Holzoptik
• langlebigere Materialien
• bessere Akustikleistung

Gerade bei großen Wandflächen ist der Qualitätsunterschied deutlich sichtbar.
