Incoming sound waves enter the small holes inside, diffuse, and undergo friction with the surrounding wall, viscous resistance, and vibration of small fibers of the material, which are converted into thermal energy and absorbed, and the sound absorption effect is achieved by attenuating the reflected sound waves. To do. It absorbs a wide range of frequencies that bother you in your daily life and improves the sounds in your living environment. On average, it can maintain a sound absorption rate of 39% for low frequencies, 80% for medium frequencies, and 88% for high frequencies. *This is a measured value based on an experimental environment. These numbers are for reference only.    Safety: Made from polyester fiber, it is safe to touch the human body without any tingling sensation! No adhesive is used, and the amount of formaldehyde emitted has reached JAS formaldehyde emission standard F4. The sound-absorbing board is flame-retardant and has self-extinguishing properties that automatically extinguish the fire when it is removed. Also, even if it burns, no toxic gas will be released. The dense porous structure provides cushioning and can also protect people and objects from collisions.    Durability: The sound absorption board is produced with high-density polyester fiber, which has good wear resistance and rigidity, and is not easy to pill and will not lose its shape even after long-term use. The fiber has almost no moisture absorption and dries easily, allowing moisture to drain smoothly from the wall, maintaining insulation performance and preventing condensation. Workability: Acoustic board can be easily cut with a cutter or other blade, so it can be used indoors. It can be processed to fit the required size of walls, pillars, floors, etc. There are also various processing methods such as 3D embossing, die cutting, laser cutting, and bonding. It can be easily fixed using ``insect pins''\/``hot melt'' and ``curing tape,'' making it possible to DIY in rental homes.    \n\u003cbr\u003e\u003cbr\u003e \u003cbr\u003e\u003cbr\u003e","brand":"Mega Shop Japan","offers":[{"title":"Default","offer_id":49137721278784,"sku":"B09K7M8XTL","price":128.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0853\/2584\/0704\/files\/61tQEAdPKZL._AC_US1200.jpg?v=1719011479","url":"https:\/\/megashopjapan.com\/products\/soundproofing-material-sound-absorbing-board-sound-absorbing-sheet-60-60cm-thickness-0-9cm-soundproofing-sheet-hard-sound-absorbing-felt-board-sound-absorbing-panel-sound-absorption-high-density-moisture-proof-for-walls-and-floors-polyester-f","provider":"Mega Shop Japan","version":"1.0","type":"link"}
