ECHO FELT - PET Acoustic Panel

ECHO FELT is part of DECIBEL’s collection of high-performance PET acoustic panels crafted to improve both the sound and visual atmosphere of any space. Designed with sustainability and creativity in mind, ECHO FELT transforms interiors into balanced sound environments while complementing any aesthetic concept.

Made from recyclable polyester felt (65% recycled content), these panels reduce acoustic reverberation, improve speech clarity, and contribute to a calm, focused atmosphere. Whether used in open offices, hospitality venues, or creative spaces, ECHO FELT delivers acoustic performance that feels as refined as it looks.

How It Works

Each ECHO FELT panel is engineered to absorb mid- and high-frequency sounds, reducing unwanted reflections and echo. Installed on walls or ceilings, the PET felt surface acts as a soft, porous barrier that traps airborne sound waves and transforms them into thermal energy. The result is clearer communication, improved concentration, and greater comfort in any environment.
