TroyStudio Acoustic Studio Absorption Foam Panel, 12 X 12 X 2 inches Pack of 18, Broadband Sound Absorber, Periodic Groove Structure Sound Absorbing Foam, Thick Dense 3D Decorative Wall Panels

The TroyStudio Acoustic Studio Absorption Foam Panel has a unique periodic groove structure to absorb certain frequencies of sound. While not effective in soundproofing a room, these panels can help reduce reflected sound. Double-sided tape or screws can be used to hang them, but screws will leave holes on the wall surface. The panels take a while to expand after being compressed during shipping. However, some of the panels cannot expand well; therefore, the product doesn't meet users’ expectations. Some customers complained about the chemical smell, lightweight, low density, and faded color of the panels, the horrible value for money, and the fact that the panels are rubbish. Although some of the reviews are negative, the product has one positive review, which confirms that the panels reduced the sound by 70-80% or more, and the user had to purchase more panels for windows afterward.
