18 Pack Self-Adhesive Acoustic Panels, 12x12 Tiles (grey)

【Echo and Noise Reduction】These acoustic panels effectively absorb flutter echoes and reverberations, improving room acoustics and speech clarity. Their dense structure reduces sound reflections off hard surfaces, making speech and audio playback noticeably cleaner and clearer for meetings, streaming, or listening.
【Self-Adhesive Wall Mounting】Thanks to a ready-to-stick adhesive backing, each panel attaches securely to clean, smooth surfaces without the need for additional tape, spray, or drilling. Simply peel off the protective film and press firmly to install acoustic wall treatment in minutes.
【High-Density Fire-Retardant Polyester Fiber】Made of odorless, high-density polyester fiber, these sound-absorbing panels resist wear and deformation during extended use. The fire-retardant material maintains structural stability without crumbling or emitting harsh chemical odors, ensuring safe daily use in shared living spaces.
