- Reduces unwanted waves, reverberation, and tremor echoes to improve overall sound clarity. This helps voices and music come through more clearly. - Also suitable as wall decoration for sound insulation in bedrooms and other living spaces. - Coverage and sizing: Each acoustic wall panel is about 1 square foot. A 12-pack covers 12 square feet. The larger the coverage area, the greater the sound insulation effect. - Easy to install and remove: The panels have a self-adhesive backing, so no extra purchase is required. The polyester material is easy to cut and can be stuck to a variety of surfaces such as doors, walls, fabric, and glass. - Installation and removal tips: You may need a bellows if you want to install, remove, or reposition the panels without damaging the surface. Blow hot air onto the surface of the acoustic plate until it becomes soft and can be easily removed from the wall. - Material and compatibility: Made from polyester and finished with a self-adhesive backing for straightforward mounting on common interior surfaces including doors, walls, fabric, and glass. Use scenarios: - Home theater or music room: Install across walls to reduce reflections and improve dialogue and music clarity. - Bedroom or living space: Combine performance with decoration to create a quieter, more relaxed environment. - Office, conference room, or studio: Use in work or recording spaces to control reverberation and improve intelligibility during meetings, podcasts, or voice recording.
