PET (Polyethylene Terephthalate) Felt is a sustainable interior product with outstanding acoustic performance. But how exactly does it work and which problems can it solve?

 

HOW PET FELT WORKS

The main acoustic effect that PET Felt has is sound absorption. What exactly does it mean?  When a sound encounters a material, several processes take place. Depending on its nature, a material can absorb the sound energy by transforming it into heat. If the sound energy is absorbed only partly, the rest of it will travel through the material. Another scenario is that a material will reflect the sound waves.

 

There are three ways that sound energy is dissipated in a porous material:

• By friction between air and the porous material which is also transferred into heat

• Through viscous effects within the air that is trapped inside the porous material, which is transferred into heat

• Through damping of the sound energy by setting the material into motion with sound pressure, which transfers the sound energy into kinetic energy.

Thanks to the production technique, PET Felt panels have an optimal structure and thickness to serve as an effective absorber.

FAQ's ABOUT ACOUSTICS

Q1. What is acoustic material for walls?
Ans: It is a sound-absorbing or blocking material applied on walls to reduce echo and noise reflections.

​

Q2. What are acoustic treatment materials?
Ans: They are materials designed to absorb, diffuse, or block sound to improve acoustic comfort.

 

Q3. Where are acoustic wall panels used?
Ans: Offices, studios, auditoriums, hospitality spaces, residential interiors and many other settings.

 

Q4. What is the difference between acoustic panels and soundproofing sheets?
Ans: Panels absorb sound within a room; sheets block sound transmission between spaces.

 

Q5. Are PET acoustic panels sustainable?
Ans: Yes, they are made from recycled PET fibers and they are environmentally friendly.

 

Q6. Do wooden acoustic panels absorb sound effectively?
Ans: Yes, perforated and grooved wood panels provide strong resonance absorption.

 

Q7. What is mass loaded vinyl used for?
Ans: It is used as a sound barrier in walls, floors, and ceilings to block noise.

 

Q8. Can acoustic spray be applied on any surface?
Ans: Yes, it adheres to flat, curved, and complex surfaces seamlessly.

 

Q9. Do acoustic ceilings improve office acoustics?
Ans: Yes, they reduce ambient noise and improve speech clarity in open spaces.

 

Q10. How to choose the right acoustic material?
Ans: Selection depends on noise type, frequency range, application area, and design requirements.​​​​​​​​​​​​​​​
