How do PET felt acoustic wall panels absorb sound?
Acoustic issues, such as reverberation and disruptive background noise, can significantly impact the atmosphere and functionality of a space. PET felt acoustic wall panels offer a stylish and effective solution for absorbing sound and creating a comfortable acoustic environment. But how exactly does this work? In this blog, we explain how PET felt absorbs sound and why these panels are a smart choice for various interiors.
What is PET felt?
PET-vilt is een duurzaam materiaal gemaakt van gerecyclede PET-flessen. Door een proces van verhitting en samendrukken worden de plastic vezels omgezet in een stevig en flexibel vilt met uitstekende akoestische eigenschappen. Deze vezels zijn poreus. Deze kleine poriën/ gaatjes absorberen geluid. Het wordt niet meer of minder terug gekaatst. Dit materiaal is niet alleen milieuvriendelijk, maar ook lichtgewicht, eenvoudig te installeren en verkrijgbaar in diverse kleuren en designs. Of je van Japandi houdt of van andere interieurstijlen, er is voor elke stijl een kleur te vinden.
The science behind sound absorption
Geluid beweegt zich voort in de vorm van golven die door lucht of andere materialen worden overgedragen. Wanneer deze geluidsgolven tegen harde oppervlakken, zoals beton, glas of metaal, weerkaatsen, ontstaat er galm. Dit kan zorgen voor een onprettige akoestiek in ruimtes zoals kantoren, restaurants of woonkamers. Maar ook in cafés, restaurants, sportzalen en sportscholen.
PET felt acoustic wall panels operate based on three acoustic principles:
-
Sound absorption
- The open structure of PET felt ensures that sound waves are not reflected but instead penetrate the material, thereby reducing noise.
-
Sound propagation
- In addition to sound absorption, the structures of the felt panels help to diffuse and break up sound waves, creating a balanced and comfortable acoustic environment.

- Installing PET felt panels in strategic locations, such as walls and ceilings, reduces reverberation and makes the acoustics in the room more pleasant.
Why are PET felt panels so effective?
PET felt has several properties that contribute to its sound-absorbing effectiveness:
✔ Dense yet breathable structure
The fibers of PET felt are tightly compressed, yet they contain small openings that absorb sound waves rather than reflecting them.
✔ Variable thicknesses for different frequencies
Thicker PET felt panels absorb a broader spectrum of sound waves, including low frequencies (such as deep voices and bass sounds), while thinner panels are effective at absorbing high frequencies (such as speech and the clinking of dishes).
✔ Flexible and modular design
’s PET felt panels can be combined in various sizes and shapes, depending on a room’s acoustic needs. Do you want to install the panels side by side or at an angle? You can install them horizontally, vertically, or diagonally.
✔ Sustainable and eco-friendly
Because these panels are made largely from recycled plastic, they are a more sustainable alternative to traditional sound-absorbing materials such as foam or mineral wool.
✔Suitable for any space
Acoustic panels can be used practically anywhere. Where do you spend a lot of time and are bothered by noise? We install these panels not only in living rooms or bedrooms at home, but also in waiting rooms—such as those at the dentist or doctor’s office—as well as in offices. Think of meeting rooms or individual workstations.
