Acoustic Foam Panels Size: 500x500x50 mm Acoustic foam absorbs sound and reduces reflections, eliminating humming and echo. Its open-cell structure converts sound energy into heat, while the 3D wedge pattern scatters reflected waves for a cleaner, more powerful sound. Ideal for vocal booths, studios, and soundproofing when combined with bass traps.
