The higher the density and the thicker the sponge, the higher the sound absorption and sound insulation effects! Compared to others, the soundproofing panel uses a high-density, extra-thick sponge of 5 cm thickness and 25 kg/m³, which is thick and highly resilient, further doubling the soundproofing efficiency. You can enjoy high-quality sound in a quieter and more comfortable environment. ✅ YOPIN sound-absorbing material is designed by professional acoustics, and the advantages are as follows: ① The wedge-shaped and pyramid-shaped structures reduce and absorb unwanted reverberation and echo, resulting in excellent sound absorption. ② It is impact-resistant and highly resilient, making it difficult to deform and protecting against impacts. ③ It is also a good insulation material. There is air inside the porous urethane foam, which blocks heat from the outside and maintains the room temperature at the same time. ✅ To achieve the best soundproofing and sound insulation effects, it is recommended that the sound-absorbing board be installed on more than 70% of the room's walls. If you want to improve the sound quality of a part of the room, you can simply install the sound-absorbing board on a microphone isolation shield or a nearby wall. ✅ The product is packaged in a compressed state. After unpacking the product, soak it in water for about 10-15 minutes, wring it out, and let it dry to restore it. Also, do not install it on uneven surfaces or surfaces with dirt. If moisture, dust, or oil stains remain on the installation surface, it may cause peeling. This is not a product defect. Depending on the condition of the wall, please purchase double-sided tape or spray adhesive separately. $$4980
