BXIThickened Sound Absorbing Panels - 12 Pack 12 X 12 X 0.5 Inches Dense Acoustic Panels, Echo Noise Reducing Sound Panels, Tackable Studio Panels for Wall and Ceiling Acoustic Treatment

Excellent product. Quality is outstanding and thick than most other panels. I no longer hear my neighbors who like to stand outside my bedroom window and hang out. (Creepy)Also BXI has incredible customer service.If I need more in the future I will buy from them.

The panels are closer to 0.4 inches than 0.5, but other than that work quite well, especially for stopping reflection of high frequency noises.

I am attempting to make a bedroom into a sanctuary as I live next door to a place with regular loud drums and music regularly. I bought 2 dozen panels and spaced them out around the walls and door so that when sound comes in, it is diffused off of these surfaces. As many people point out, these panels don't block outside noise completely but they do dull it to a level that makes it tolerable for me; I also bought some noise cancelling curtains and put down some thick rugs. With this combination, I am happy with the results; they passed the " clap test" even without the other adjustments which means they have effectively deadened the room sound. At a certain point I may buy more to help disperse sound in other rooms as well.The panels are light and easy to hang, and the neutral color does not distract.TL:DR- these are a great purchase but don't expect these alone to do the job.

They only measure 11" 5/32, which really throughs things off when trying to glue them to a 4x8 sheet of Styrofoam insulation or plywood. why say your 12x12 and then shave off 3/16? just make it 12x12. This comes out to exactly 30cm metric, then they just round up for advertising.

Very happy with the purchase it does the job pretty well

Sticks very well onto my entrance door using indoor 3M tape. There is definitely a difference with the amount of sound entering my apartment. I have a dog who is very anxious and this helps tons. Did research and for best results, recommended to use a vinyl wrap first then have these installed on top. Great product.

I have 12 panels on each wall and didn’t do a single thing. The sounds are still the exact same. I just have squares secured to my walls now as decorations.

I really wish folks would publish specs for absorption vs frequency. These things are very dense and seem to be effective only in the 15K and up range. They were pretty useless for helping with "first reflection" in the upper midrange. They do make a fine bulletin for posting notes. two packs and a lot of work, probably headed for the trash.
