4-Pack Self-Adhesive Acoustic Wall Panels — 3D Perforated Tri-Layer Polyester Fiber Insulation, Elliptical-Line, 24×12×1.78"

- Tri-layer Composite Structure: Two outer layers of high-density polyester fibreboard encase a high-density porous sound-absorbing cotton core; UV printing reproduces 0.1mm wood-grain detail while <1mm precision engraving creates 3D perforated wood-grain surfaces that form a three-dimensional light-and-sound transmitting pattern, turning sound absorption into a visible design element. - Audio Clarity Performance: Constructed from a high-density 230 kg/m³ 100% polyester fiber substrate combined with 35 kg/m³ polyurethane foam and >95% porosity, these panels effectively absorb echoes, reverberation, vibration and standing waves, reduce low-frequency background noise as well as mid-to-high frequencies, and preserve a clean acoustic field for recording and playback while keeping indoor spaces quieter. - Versatile Application Scenarios: Modular panels suit professional studios, home theaters, studies and gaming rooms; they deliver acoustic optimization and aesthetic enhancement simultaneously, enabling immersive movie experiences, improved concentration and an attractive backdrop while combining soundproofing, fire-resistance and decorative functions to replace bulky traditional wood panelling plus separate acoustic and fire materials. - Quick, Flexible Installation: Modular free-assembly design allows horizontal or vertical seamless splicing; high-tack adhesive covers the full back surface so no extra glue is required; typical installation completes in about 5 minutes, cutting installation time by up to 60%; panels are medium-sized for adaptable wall coverage and DIY-friendly—heat with a hair dryer before removal to protect wall finishes. - Handcrafted Specs & Options: Sold as a 4-panel pack, each panel measures 24×12×1.78" and one pack covers approximately 7.7 sq ft; available in three color schemes and nine perforation patterns; lightweight for creative layouts, cut using CNC technology for millimetre-level accuracy, with perforated edges hand-sanded and polished; defect rate maintained below 0.3%.
