Product Description: Environmentally friendly material: The acoustic panels are made of 100% polyester fibers, which are flame-retardant, sound-absorbing, odorless, non-toxic, and durable. They are safe for children, pets, and adults and offer better sound insulation than conventional felt panels. Easy installation: Equipped with a self-adhesive backing, the panels are easy to install. Simply peel off the protective film and attach them directly to the desired location without the need for additional glue or tape. Efficient noise reduction: The acoustic panels minimize reverberation and reduce distracting noise. They absorb sound at low, mid, and high frequencies, making them ideal for recording, mixing, or other acoustically sensitive applications. Stylish and flexible design: Easy to cut and customize without compromising sound absorption. The modern design of the panels also makes them suitable as a decorative element, combining functionality with aesthetics. Versatile: Perfect for offices, studios, rehearsal rooms, concert halls, and other environments where a quiet atmosphere or improved acoustics is required. Effectively filter out unwanted noise and create a pleasant environment.
