This document describes acoustic panels from a Swiss company called Calmness. The panels are modular and customizable with different fabric and color options. They are designed to optimize acoustics in rooms by reducing noise, echoes, and reverberation. The panels absorb sound through an open, porous material structure and layers of acoustic fleece. They can be placed on walls, ceilings, or as room dividers to improve acoustics up to 25% of the floor space. Examples of installations are provided for hospitals, schools, and senior living facilities in Switzerland.
