(Density: 30kg/m3) [Principle of sound absorption] When sound hits the porous urethane sponge sound absorbing material through air propagation, the sound vibrations are transmitted to the air bubbles inside the urethane material. Inside the bubble, the vibration of the transmitted sound causes a phenomenon of viscous friction in the air, which converts the energy of the incident sound into thermal energy, creating a sound absorption effect. (Please note: It cannot be completely soundproofed) [Applicable scenes] Suitable for use in various places such as studios, recording rooms, bedrooms, construction sites, karaoke, etc. In addition, because it is lightweight and flexible, it has excellent operability and processability, and can be freely DIYed according to demand.
