18 Pack Black Acoustic Panels 12"X12"X 0.4"Sound Absorbing Panel Wall Decoration Soundproof Wall Panels High-Density Sound Deadening Panels Acoustic Treatment Panel For Home Studio

Bought these for my golf sim project and they look great. I've clobbered them pretty good and they held up with no noticable deformation. The room doubles as a movie theater and they really help with the acoustics. The adhesive is very convenient and strong. Might take the paint off but I have no intention of removing them.

Week 1. We do about an hour each night after work. They look and sound great. Already cutting out echo / reverb.DO NOT MAKE A MISTAKE. They require perfect placement. Once it sticks its not coming off. That was really comforting because this is a permanent investment we're making.Update : Easter May 31st.We had some free time after church and decided to give today another strong push. We've been very carefully aligning and measure ever piece. Reminder when tracing the circles for the cuts you're aligning direction of the way the tile is facing. We had one tile cut backwards.Sheers for cutting siding are great for straight lines but for circles I'm carefully tracing each circle on the backside and puncturing with a utility knife and carefully cutting the outline like you do with cutting glass.We have not had a single marred tile or messed up texture.Our plan is to lay all of the big sections the go in and use the scraps to fill the small gaps.

Caution #1-the ad describes these as 12" square and they are not. More like 11 3/4" square. Not a deal breaker, but if you are counting on filling a 12" space, you'll be let down. Caution #2-I'm not so sure how well they will perform, but I also do not expect a miracle from a sound deadening product that is only a half inch thick. I have a home studio with a pair of 24" closet doors directly behind me when seated at the desk and was getting some low frequency reflection from the large flat(ish) surface. As I could not do the traditional rock wool thick panels on the doors, I figured these would be better than no treatment(and they are). I over-wrapped with red jute fabric to match the rest of my panels. They stick well(mounted them on a thin sheet of plywood that hangs from the top of the door so no damage if I ever remove them). As long as your expectations are reasonable, these are a great value.

Pretty impressed with these tiles!! Don’t believe all the negative reviews! Some people…. These are SUPER sticky and will not fall off! They WILL take the paint off if you try to remove them after they have been applied for some time! I would even go as far as say they will take the paint off as well as the paper backing on the drywall! They stick that good! I’m applying them onto painted cinder block walls in a basement theater! Works great!I highly doubt they would classify as sound proofing though! But that’s next to impossible with any product being only .4 inches thick I mean come on. They don’t even work as sound absorbers for in room acoustics. But I wanted them more for just wall coverings and to stop the projector from illuminating the walls and to keep the room warmer which they do quite well!! They act as a great insulator from the cold block wall.Fairly good color uniformity! Some slight differences from box to box. I have gone thru 7 boxes so far. To get the paper backing off the sticky side try to scratch if off in the corner instead of trying peeling it to start. I could make a video to show but it’s not that difficult. Once you get it started and separated from the glue the paper comes right off. It’s not rocket science lol.Overall great product! Would recommend for someone using in a similar situation. But would NOT get on the sole purpose of sound proofing a room. You’d be better off double drywall/Sheetrock instead. Almost the same price as these are $2 a square foot.

I stacked these inside my window panes, and the area above, within my bedroom. I covered all of the glass with a layer of 2 panels. This greatly reduced the noise coming in my window. The walls in my room already block noise well, so I didn't have to use them on anything but the window. My sound machine used to struggle to drown out these noises, but now I hardly hear any cars drive by, lawn mowers, etc.

These are such as great deal for reflections in bad spaces. I used finishing nails to hook on my drywall. The adhesive is really good but if I remove these, I'd rather take care of pin holes instead of tearing up drywall paper.

The noise cancelation and adhesive seems fine. They are pretty precisely made, but they seem to be 300mm not 12"Over a large project the shortage matters and you will need to order more. I would have bought a different brand had I known, as I needed exact footage. Now I need to order more and cut them down. They did cut pretty easily with a laser cutter, only a little smelly.

I bought these for my bar/Tavern, as it is a square (relatively) room and echoes horrible. With the correct placements of these throughout the bar, it made a phenomenal difference, and I am looking to purchase more in the future.
