(High Density and Thickness, Excellent Sound Absorption Effect) If the sound absorbing material has a certain thickness, it has a certain sound absorption rate even in middle or treble ranges, but in the bass range, the thicker the sound absorption rate is higher. In addition, the frequency of sound that people feel uncomfortable in daily life is over 2,000 Hz (treble range). And our sound absorbing panel is 9mm thick, combined with a density of 230kg/m3, the same thickness sound absorbing board has an average of 88% high sound absorption rate of 88% in high frequency frequencies, but it also has a sound absorption effect of 80% against midrange and 39% in bass range "0Hz to 250Hz". You can expect to thoroughly improve the sound environment with this single item. (Saves on your energy bills just by sticking on) Made of high-density 100% polyester fiber that is 58.6 lbs (230 kg) / m3, the porous structure effectively traps heat and the polyester does not deteriorate easily, so you can expect a lasting insulation effect. By testing for heat preservation and insulation (when applied to the entire wall and floor of a room), our sound absorbing material and sound absorbing panel has been proven to have a thermal effect of about 45%, and the insulation effect is about 60% (heat preservation and insulation rate = temperature difference before and after sound absorption board is used) In addition to being safe, flameproof, environmental, heat insulation, sound absorption, and water permeability are also very good. (Easy to Cut with Blades) Easy to cut through scissors and cutters, our sound absorbing material and sound absorbing panels are made of high-density 100% polyester fiber that is rated at 58.6 lbs (230 kg) per m3 density, and can be cut with precision equipment, and inspected by staff to minimize the overall thickness of the sound absorbing board, and can be adjusted to the size you need. (Easy to install with 3M double-sided tape as gift) The 3M double sided tape has been firmly made than standard double-sided tape that will fall off quickly, so we only offer 3M double sided tape for sound absorption and sound absorption panels. In addition, there are various processing methods such as 3D embossing, die-cutting, laser cutting, and gluing. It is easy to fix with "insect pin" / "hot melt" and "curing tape" and can be DIY in rental houses (items required in this case are sold separately). 【Can be used anywhere】It can make your office more silent and clean audio recording. It can also be used in professional studio, rehearsal room, concert hall, podcasting, church, home theater, vocal booth, home studio, etc. [Product Specifications] Sound Absorbing Material Size: 11.8 x 11.8 x 0.3 inches (30 x 30 x 0.9 cm) (Weight: 4.2 oz (125 g); Sound Absorbing Material: 100% polyester fiber.
