TETRIS FELT - PET Acoustic Panel

TETRIS FELT is part of DECIBEL’s collection of innovative PET acoustic panels that combine sound absorption with creative design possibilities. Inspired by geometric balance and modular rhythm, TETRIS FELT brings a dynamic sense of movement to walls and ceilings while improving overall acoustic comfort.

Made from recyclable polyester felt (65% recycled content), TETRIS FELT is both eco-conscious and performance-driven. It softens echo, enhances speech clarity, and transforms noisy interiors into calm, harmonious spaces.

How It Works

Each TETRIS FELT panel absorbs mid- and high-frequency sounds by trapping sound waves within its soft PET fibre matrix. When arranged in modular patterns, the bevelled surfaces and variable geometry help diffuse reflections and scatter noise evenly across the room. The result is a balanced acoustic environment that looks as refined as it sounds.
