HERTBER Self-Adhesive Acoustic Foam Panels, 12" x 12" x 1" Sound Proofing Padding for Wall, High Density Sound Absorbing Panels for Studio & Home Office 36 Pack

[Fast Expansion & Resilient Foam]Our acoustic foam panels feature superior resilience, regaining their full shape and size shortly after unboxing. Even after long-term vacuum sealing, they typically puff up within hours. Pro Tip: Use a hair dryer on a low heat setting to blow across the surface to accelerate the expansion process for a perfect, uniform shape.

[Strong Self-Adhesive – No Extra Glue]Skip the mess and cost of spray adhesives! These panels come with a premium full-coverage self-adhesive backing. Just peel off the protective film and stick to any clean, smooth surface. It’s the ultimate "Peel and Stick" solution for a hassle-free studio setup. (Note: Do not soak in water to protect the adhesive).

[High-Density Sound Absorption]Made from professional-grade 25kg/m³ high-density polyurethane foam, these 1-inch thick panels effectively target mid-to-high frequency sounds. They are engineered to eliminate echoes, flutter echoes, and standing waves, ensuring crystal-clear audio for recording or gaming.

They are completely safe for use in home offices, bedrooms, schools, and recording studios, providing a healthy environment for your creativity.
