Upgraded Acoustic Panels: The larger panel design helps to disperse more noise and eliminate echoes more effectively than smaller panels. Excellent Sound Absorption: The sound waves interact continuously with the high-density 100% polyester, causing the sound to gradually lose energy, which reduces echoes and absorbs noise. Self Adhesive Design: Easy DIY installation just peel and stick—no extra purchases needed. Transform your space in a single day without any special skills. High-Density Material: Made of 100% polyester for superior sound insulation compared to foam panels. Our panels are flame-retardant, odorless, formaldehyde-free, corrosion-resistant, and fade-proof. Wide Application: Ideal soundproofing for walls and ceilings in recording studios, podcast booths, home studios, and more. Also great for offices, home theaters, game rooms, man caves.
