Foam Panel Category — 4-Pack, 48 × 24 × 2-inch “Egg-Crate” Acoustic Foam; For Wall Soundproofing, Studio Acoustic Treatment, and Echo Absorption

When you require acoustic coverage for a large surface area, a single, oversized foam panel represents the most economical and efficient solution. This 48 × 24 × 2-inch (4 ft × 2 ft) “egg-crate” style acoustic foam panel is constructed from open-cell polyurethane with a density of approximately 20 kg/m³. The egg-crate contours feature a depth of about 0.8 inches, creating a dense acoustic labyrinth. Each panel covers an expansive area of ​​8 square feet—sufficient to treat a small wall section or a desktop partition. The egg-crate design excels at absorbing frequencies within the human vocal range (500 Hz – 4 kHz), effectively reducing flutter echoes and reverberation within a room. The material is lightweight and pliable, allowing for easy installation using spray adhesive or double-sided tape. Typical Applications: Covering an entire back wall in a home studio, lining the ceiling of a podcast booth, or serving as a temporary sound barrier around a drum kit. The single-panel packaging also makes it convenient for testing purposes—you can hang it at a primary reflection point to personally experience the degree of sound improvement. Available in black or gray color options; this specific model is the standard black version.
