[Excellent Soundproofing] The soundproofing boards have been increased to a thickness of 2mm, achieving a surface density of approximately 3.5kg/㎡. Test results show that this surface density provides excellent soundproofing performance with an acoustic transmission loss of 23dB at a frequency of 1000Hz, maximizing soundproofing effects without affecting communication environments.
[Easy Installation] Moon River soundproofing material overcomes the difficulty of handling traditional roll-type materials by improving the size of the soundproofing sheets to 30cm x 30cm. Precisely processed, each sheet weighs only 0.32kg, making it easy for even beginners to install.
[Safe Material] The main material of the soundproofing panels is soft PVC. It is environmentally friendly and flame-retardant, ensuring safe use. It can be used in various settings such as audio rooms, studios, home theaters, soundproofing walls in apartments, and car sound deadening.
[Usage Advice] It is recommended to install the soundproofing material on the wall or floor where noise is coming from to block noise at its source. It is recommended to cover more than 70% of the room's walls for installation. Using it in conjunction with compatible Moon River sound-absorbing materials will provide synergistic effects, significantly enhancing sound absorption and soundproofing performance.
