Large, 50cm wide, black, compressed, sound-absorbing, soundproofing urethane sponge (2cm thick, set of 2 high-quality sheets)

The open-cell urethane foam attenuates sound itself, reducing transmitted sound. Its wavy shape effectively disperses reflected sound and suppresses reverberation. This product is a compressed type, so please allow it to return to its original shape for several hours to several days after opening. If it does not return to its original shape, soak it in water, wring it out thoroughly, and dry it in a dryer for several days before using. It is useful for recording music in karaoke rooms, professional music production for vocalists and guitarists, YouTube video production, live music venues, home theaters, and music listening on audio equipment. It can also be used for a variety of purposes, such as preventing neighbors from hearing babies and pets, creating and repairing soundproof covers for pumps, generators, and compressors, and as cushioning for various storage covers for musical instruments, cameras, and computers. We offer low prices thanks to our bulk purchasing. Size: W500mm D500mm H20mm Set Contents: Set of 2 (compressed type)
