These wall panels are designed to help regulate room acoustics by absorbing a wide range of sounds. Each panel is built from a dense polyester composition that provides structural stability and effective sound absorption. With a high density material around 14.35 lb./ft³, the panels work to minimize echoes and reverberation, making conversations clearer and music less lively in untreated rooms. The noise reduction is measured with an NRC rating above 0.95, indicating strong performance across mid to high and low frequencies. As more panels are installed, the overall absorption improves, allowing you to tailor the treatment to the space. The panels use a simple peel and stick backing that adheres to walls, doors, windows, or ceilings without the need for additional tape or spray adhesives, saving time and reducing mess. The surface features a brick style three-dimensional design that adds visual interest while not compromising acoustic function. The set includes 20 pieces, each 12 by 12 by 0.4 in. covering roughly 20 sq. ft. in typical layouts. They are made from 100 percent polyester, which is odorless and non-toxic, emphasizing safety in homes, studios, and offices. This combination of performance, ease of use, and aesthetics makes them suitable for recording spaces, control rooms, home theaters, and other areas where speech clarity and quiet are desirable.
