4 PACK - Acoustic Foam Panels Wedge 140 50x50cm | Sound Proofing Padding For Wall | Studio Absorbing Insulation

The "Wedge 140" panel comprises 25 individual elements, each measuring 10x10 cm (4"x4"), which can be assembled into a single panel measuring 50x50cm (20"x20").

These sound-absorbing panels utilize a special microporous structure of the acoustic foam to transform sound energy into thermal energy, effectively absorbing it. Additionally, the 3D surface of the panel partially scatters reflected sound, attenuating mid- and high-frequency sounds and resulting in a cleaner and more powerful overall sound.

Acoustic polyurethane foam panels offer several advantages over other sound-absorbing materials, including a high noise reduction coefficient (NRC), lightweight construction for easy transportation and installation, compatibility with most surface types and shapes, and aesthetically pleasing surface patterns.

The variety of profile shapes allows these panels to double as contemporary wall finishes, providing both a professional look and functional sound absorption. Whether setting up a recording studio, an audition room, or any other enclosed space requiring a special sound environment, acoustic foam panels offer an excellent solution.

Please note that acoustic foam is supplied in a compressed form to reduce shipping costs. It should be unpacked and left to restore its shape in a warm room for optimal performance. Some pores may be larger than others, which is normal for acoustic foam and does not affect performance.
