AGPTEK Sound-Absorbing Material, 30301cm (12 Sheets, Black), Fully Adhesive, High-Density, Self-Adhesive Soundproofing Material, Rigid

[Excellent Sound Absorption] AGPTEK soundproofing boards are conveniently sized at 30*30*0.9cm. The high-density board absorbs low, mid, and high frequency sounds from all sides. Their sound absorption is approximately 2.5 times stronger than other products. [Carefully Selected Materials] Made from environmentally friendly, flame-retardant, odorless 100% polyester fiber. They not only absorb sound, but also have excellent heat retention and insulation properties. They are less likely to deform over time than foam soundproofing boards, making them easy to clean. [Wide Range of Applications] AGPTEK sound-absorbing material is ideal for reducing costs and improving recording quality in homes and recording studios. It is also suitable for a variety of locations, including piano rooms, audio rooms, offices, conference rooms, rooms, churches, soundproof rooms, and anechoic chambers. [Easy Installation] No additional adhesives are required; simply peel off the double-sided tape on the back of the soundproofing board and stick it to the desired location. Use a knife to cut soundproofing boards to any size. [Set contents] 12 black soundproofing panels with double-sided tape on the back. Size: 30*30*0.9cm.
