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

Acoustic foam serves as a sound-absorbing finishing material in environments that demand clear, resonant sound free of unwanted noise reflections. Its open-cell structure allows the "Pyramid" sound-absorbing foam to convert sound energy into heat, effectively absorbing it. Additionally, the 3D surface patterns scatter reflected sound, attenuating mid- and high-frequency sounds and resulting in a cleaner and more powerful overall sound.

Key specifications for the "Pyramid" acoustic foam include:

- Dimensions: 50x50cm / (20 х 20 inches)
- Thickness: Available in three options: 3cm - 5cm - 7cm / (1.3" - 2.1" - 2.9")
- Material: Open-cell polyurethane foam
- Density: 25 kg/m3 / (1.8 lb/ft3)
- NRC range: Approximately 0.2 — 0.94
- Compression strain: 3.7 - 4.3 kPa (40% compression)
- Permanent deformation: Up to 3.6% (22 h. 50% compression at 158 °F)
- Tensile strength: From 90 kPa
- Temperature resistance: Approximately 122 °F
- Number of pores per 1 cm2: About 400
- Number of large pores per m2: ≦ 1%
- Panel thickness error margin: Up to 0.5 cm / (0.2 inches)
- Panel area error margin: Up to 1 cm / (0.4 inches)
- CIELAB chromatic error range: Delta E ≦ 5

Advantages of acoustic polyurethane foam panels over other sound-absorbing materials include 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.

It's important to note that acoustic foam is supplied in a compressed form to reduce shipping costs. After unpacking, it should be left to absorb air and restore its shape for optimal performance. Some pores may be larger than others, which is normal for acoustic foam and does not affect performance.
