12 Pack Acoustic Foam, 30 x 30 x 2.5 cm Self-Adhesive Acoustic Panel, Sound Insulation, Noise Cancelling Foam for Home, Studio and Office

The self-adhesive acoustic foam is made of high-density polyurethane material with a density of 25 kg/m³. It can quickly expand to its maximum thickness (2.5 cm) in a short time, and the material has no pungent smell. Acoustic panels are designed for sound absorption and sound insulation. Pyramid surface increases the contact area with sound waves, effectively absorbs sound waves from the environment, reduces reflected sound and echoes, improves the acoustic quality of the room, and at the same time reduces noise. The sound insulation panels have a built-in adhesive layer, so no additional adhesive tape is required. They can be installed directly on different wall surfaces. The panels are securely fixed after installation and can be easily removed without causing significant damage to the walls. The self-adhesive sound insulation is suitable for recording studios, personal studios, offices, living rooms, live broadcast rooms, private theaters or any environment requiring sound quality and noise absorption. It is also suitable for DIY sound absorption boxes. Easy to shape and cut, change will not affect performance. You will get 12 pieces of sound insulation wall with a size of 30 x 30 x 2.5 cm. Products are shipped vacuum-packed. To accelerate expansion, it is recommended to tumble dry. If the edges/corners of this pyramid foam do not recover well, you can soak them in water for 0.5 hours and then heat or air dry. Note: If some soundproof panels cannot be recovered effectively, please place them in a cool and ventilated place for 12-48 hours.
