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

The "Wedge 140-Double" panel consists of 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, effectively combating echo effects and weakening medium and high-frequency sounds, resulting in a high-quality and clean sound in the room. The "Wedge 140-Double" panel is ideal for treating studios, recording suites, home theaters, and any other audio environment in need of acoustic treatment. It is suitable for vocal booths, home studios, and various other environments, especially when combined with corner bass traps.

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 various surface types and shapes, and aesthetically pleasing surface patterns. With a variety of profile shapes available, these panels can also serve as contemporary wall finishes, providing both aesthetic appeal and functional sound absorption.

It's important to note that acoustic foam is supplied in a compressed form to reduce shipping costs. It should be unpacked and allowed to restore its shape in a warm room. Some pores in acoustic foam may be larger than others, but this is normal and does not affect performance.
