TONOR 4-Pack Bilayer Acoustic Panels 48 x 24 x 0.72 inches Self-Adhesive Grey – Large Polyester Soundproof Tiles for Echo Absorption

Overview: Four oversized, dual-layer acoustic panels from TONOR designed to reduce echo and improve room acoustics. Each panel measures 48 x 24 x 0.72 inches and uses a bilayer, thickened absorption construction to disperse sound more effectively than single-layer options. Performance & Size: The larger surface area and double-layer design deliver enhanced noise diffusion and echo reduction across wide spaces. This 4-pack provides extensive coverage for studios, living rooms, bedrooms, home theaters, and other listening environments. Installation: Panels feature a self-adhesive backing with a strong adhesive—just peel and stick to smooth surfaces. No extra tape required. The adhesive is formulated to protect your walls and hold panels securely in place. Appearance & Custom Fit: Finished with a stylish stripe pattern, these tiles work as both acoustic treatment and wall décor. They can be trimmed to fit irregular layouts or smaller rooms without reducing their sound-absorbing effectiveness. Materials & Safety: Constructed from 100% high-density polyester fiber. The surface is heat-treated for a durable texture. The material is non-toxic, odorless, and formaldehyde-free, safe for adults, children, and pets to breathe and touch. Packaging & Support: Units ship with reinforced corner protection to minimize transit damage. If you are not satisfied, contact us—our professional acoustic engineers will assess your situation.
