Foldable perforated sound absorbing panels offer a practical and reusable acoustic solution for temporary spaces such as trade booths, mobile studios, and modular offices. Featuring perforated MDF or aluminum faces with internal PET or foam cores, these panels combine effective sound absorption (NRC up to 0.85) with portability. Certified to ASTM E84 and ISO 10534-2, they come in various fold styles like book-fold, accordion, or zig-zag for maximum versatility.
