iFutniew 24Pack 2X12X12Inch Self-Adhesive Acoustic Foam Panels, Pyramid Designed Sound Pannels for Home and Studio Easy to Use

Self-Adhesive: Our soundproof foam board features a self-adhesive layer. No need for additional glue or tape. Just peel and stick anywhere. Strong adhesive ensures secure attachment on walls without worry of it falling off. They improve sound clarity and reduce harshness when installed on walls or ceilings. Perfect for studio recording, podcasts, interviews, meetings, and gaming rooms. Professional Sound Absorption: With its unique pyramid 3D acoustic design, these acoustic foam pannels increases the contact area with sound, leading to excellent absorption of flutter echoes, reverberation, and standing waves. Compared to 1inch panels, the 2inch panels provide significantly better acoustic treatment. Rapid Expansion: The acoustic panels in vacuum-sealed packaging simply need to be separated from the interlocking state and placed in a well-ventilated area. Typically, they will fully expand to their complete shape and size within 24 hours.
