Features:

High-density polyester fiber:
Crafted from high-density polyester fiber, these sound-absorbing wall panels effectively absorb mid-to-high frequency noise (voice, musical instruments, office chatter), reduce echo and reverberation, and improve sound clarity.

Adhesive backing:
Each sound panel comes with pre-attached strong adhesive backing. No drilling, nails, or additional tools are needed. Simply peel off the protective film and stick the panel firmly to clean, smooth walls or ceilings (also suitable as ceiling sound-absorbing panels). The adhesive bonds tightly to most surfaces (wood, concrete, tile) and won't damage walls.
