Dekiru 18-Piece Set Of Hexagon Acoustic Panels Sound Absorbing, Self-Adhesive Product Details ?Easy to Cut and Install?Our soundproof foam panels come with adhesive backings, making them easy to install with just a peel-and-stick method, no additional tools required. For best results, ensure the wall surface is clean and smooth before installation, and avoid repositioning the panels as the adhesive may lose its effectiveness. ?Stylish Appearance?Our hexagon-shaped acoustic panels are not only effective in sound absorption, but also perfect for room decoration. The unique beveled design of the soundproof foam panels reduces noise while adding a touch of elegance to any room. Choose from a variety of colors to create your own DIY combinations. ?Improved Acoustic Quality?Our soundproof wall panels are made of high-density polyester fiber with a density of 250 kg/cubic meter, with a noise reduction coefficient (NRC) of 0.92, making them highly effective in absorbing high-frequency sounds generated by human voices or electronic devices. Pairing with low-frequency traps can absorb a wider range of frequencies. ?Eco-Friendly and Indoor Use?Our soundproofing materials are safe to touch and breathe, with no unpleasant odor. Our professional sound-absorbing panels are perfect for reducing echo in recording studios or office walls, as well as absorbing sound during gaming sessions, while also adding decorative flair to your recording studio, control room, home recording studio, home theater, and home office. ?After-Sales Service?We offer 24-hour professional customer service.
