It responds to and absorbs sound at random angles of incidence. Easy to cut with scissors, so it can be installed in various places. The back side has full-surface adhesive tape, so just peel off the release paper and stick it on. Easy to install for DIY recording booths, soundproofing measures for rooms, etc. Recommended for soundproofing walls, entrances, and toilets! Absorbs noise and improves the quietness of the car interior. Effective when applied to the outer panels behind the speakers and other door panels. Combining with damping sheets (deadening sheets) can be expected to provide even higher soundproofing effects. 【Custom Orders Available】 We also accept changes in the number of pieces and size, so please feel free to comment.
