ATS Acoustics sound deadening acoustic panels with our exclusive Guilford of Maine Sona line of acoustical fabric are the industry standard in acoustical treatment for your home, office, work, or any space or room. They are Fire Rated Class 1 or Class A per ASTM E84, and they feature a Noise Reduction Coefficient (NRC) of 1.0 out of 1 for superior sound absorption. They are built using a solid wood internal frame that protects edges from dents and damages, a highly effective noise absorbing mineral wool core, and wrapped in fire resistant Guilford of Maine fabric. These panels reduce reflections from a room's hard surfaces to keep sound clear and free from excessive reverb and echo, which is especially important when recording speech or vocals. These panels are an industry favorite among professional studios, musicians, podcasters, voice over actors, streamers, and influencers. The wide color variety can complement any room or wall decor or design with the rich colored sound absorbing fabric. Installation is easy with the included mounting template and installation hardware that can mount to most common construction materials such as drywall, concrete, and wood walls.
