SOUND AND SILENCE

PET 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.
