Thank you for viewing. Immediate purchase is OK. Size: 30*30*5cm 【Increased Thickness * High Density】The sound absorption and sound insulation effects of sound-absorbing panels are determined by the density and thickness of the sponge. The higher the density of the sponge, the thicker it is, the higher the sound absorption and sound insulation effects! Compared to others, the soundproofing panel uses a high-density, extra-thick sponge of 5cm thick and 25/ density, which is thick and highly resilient, further doubling the soundproofing efficiency. You can enjoy high-quality sound in a quieter and more comfortable environment. 【Excellent Material】YOPIN sound-absorbing material is designed by professional acoustics, and the advantages are as follows: ? Unwanted reverberation and echo are reduced and absorbed by the wedge-shaped and pyramid-shaped structures, resulting in excellent sound absorption. ? Impact-resistant and highly resilient, it is not easily deformed and protects against impacts. ? Also good as an insulation material. There is air inside the porous urethane foam, which blocks heat from the outside and at the same time maintains the indoor temperature. 【Eco-friendly and Safe, Wide Range of Applications】Please rest assured that it is made of eco-friendly and flame-retardant urethane foam material. Strong double-sided tape is included, so please refer to the operation instructions on the product page and follow them. It is also applicable in a wide range of places, such as rooms, piano rooms, audio rooms, recording studios, viewing rooms, offices, and conference rooms. Please use it according to your preference. 【Different Effects Depending on the Installation Area】To achieve the best soundproofing and sound insulation effects, it is recommended that the installation area of the sound-absorbing board be more than 70% of the walls of the room. 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. 2026-1-3-③
