Acoustic Panels 24 Pack Set 12''x12''x2'' of Acoustic Foam Panels for Recording Studios, Sound Absorbing Foam Panels for Noise Dampening and Echoes Absorption (12''x12''x2'', Black)

These work really well. I didn't wait 2 days. I had them ready to post up within 6 hours. After pulling it out of the plastic they began to rise by themselves. I quicken the process by simply gently pulling the stubborn corners in each direction. I also got them to fluff evenly all around by gently tugging opposite corners as well as the mid left side to right side. Pulling too hard would probably rip it. To rid of the smell quickly I stood each square upright in my bathroom-- some against the wall, and some leaning on each other-- so it can air out. The major thing that helped here is that I have an exhaust fan in the bathroom, and so by closing the door it sucked air through the foam even more quickly. Didn't have to stink up the house or leave it outside where allergens might grab on. As for adhesion, the thing that worked for me was letting spray adhesive on the backside, and then using velcro with the adhesive backs on them. This doesn't cancel out noise completely like some people expect here... but it definitely does a great job dampening to a large extent. I have thin windows, and the neighbor hasn't had a problem with me since.

Very disappointed my last order was never completed I only got half of my Acoustic foams instead of 24pack only got 12 and paid in full. Im still waiting for the other 12 .its almost 2months. very disappointed .. I wonder if I ever gonna get the other 12. Or is it a SCAM. KEEP IN TOUCH

Muy buenos, me dejaron el cuarto justo como esperaba

No adhesive tape in the package. Some panels are damaged

I bought this pack of 24 pyramidal acoustic panels of 12 x 12 x 2 inches to improve the acoustics of my home studio, and the truth is that they exceeded my expectations. From the first moment, I noticed a significant reduction in echoes and reverbs inside the room. The pyramidal shape helps to disperse the sound waves evenly, which improves both the quality of the recordings and the overall listening experience. The panels are of high density, which translates into more effective sound absorption compared to other thinner or less compact models. In addition, the fact that they are fire resistant gives me much more peace of mind when using them in closed spaces with electrical equipment. Another point to highlight is how easy they are to install. With a good adhesive (not included), the panels are easily fixed on both walls and ceilings. The black finish gives a professional and modern touch to the space.
