Correcting echo can also improve a room's appearance.

A bare wall reflects voices and creates a harsh sound environment. This set of 18 light gray acoustic wall panels offers a simple solution: it helps absorb reflections while creating a smooth, contemporary surface.

Each self-adhesive square measures 30 × 30 cm and is 9 mm thick. The pressed polyester fiber and light gray color easily integrate into an office, home studio, or video conferencing space.

FAQ

What is their main function?

They are designed to absorb some of the sound reflections in the room and reduce the sensation of echo.

Do they replace sound insulation?

No. They improve indoor acoustic comfort but do not, on their own, block sound transmission between two rooms.

How do I install them for lasting results?

Clean and dry the surface, test adhesion on a small area, then align the panels before pressing them firmly.
