4 Pack Acoustic Fiberglass Panels 23.6" x 11.8" Sound Absorbing Panel,Beige | UMIACOUSTICS, 2" Thick, Sound Absorbing, For Studio and Home, Includes Wall Mounting Bracket, Easy Installation

My stairwell use to be an echo chamber for every sound inside and outside my house. Hung these panels up and it is noticeably quieter. They also function to balance out the stairwell with my art on the other side. They are very durable and look very nice. The adhesive left something to be desired, so I just super glued picture hangers on the back and hung them that way.

Easy to install & they absorb most if not all of the echo & reflection distortion, made a huge difference in my surround system & my system is high quality with a dedicated OSD nero xa 5180 . my system is performing better than ever before with these panels & other foam sound absorption 12×12 panels

Our clinic has barn doors which look great aesthetically but are not great for sound so we tried these out. I was skeptical they would work but I'm pleasantly surprised. Only complaint is the first few days after putting them on the wall a few would randomly fall off. Definitely recommend letting these acclimate in the room for a day or two before sticking them up. But overall very happy. We bought more for each exam room.

Panels work great. No smell, arrive assembled you just need to mark the wall using template provided an easy secure mounting. Very happy with the reduction in conversation carryover with my wife’s office on other side of the wall.

The panels work well and are pretty good quality but the adhesive is quite bad. I stuck 5 of the panels on the wall, all side by side, and within a few days they all fell. After about 10 hours after putting them up, the first panel fell onto one of my monitors breaking it. 2 days later, the other 4 fell at almost the same time. I would still recommend getting these, but just make sure you have another way to mount them to the wall instead of relying purely on the adhesion tape. Also the panels appear to have no mount on the back to screw them in.

For my case they do a decent job. It’s not because the product isn’t good, it’s because I place them centered for aesthetics/design. In that wall I have two desks. The results can be better if placed right in front or behind your sound source. Easy to install, let’s see how long they stay up

Avoid! Last time I bought these, it was nice and easy to install with a simple adhesive backing. Now it involves construction. I absolutely would not have bought them if I knew this. Bait and switch products are the worst.

These work great and look great, what more can you ask for? I got three packs of these and wow do they make a difference when listening to my stereo system. I'm very much a believer in room treatment now and these are wifey approved. Enough said.

Excellent quality panels and excellent customer service. These panels definitely help to reduce echoes and reverberation in my home theatre room. I can't say enough about their customer service. I contacted customer service as I was looking for advice on an alternate way to hang these panels. I did not want to permanently stick the panels to the wall. Upon asking, they then explained that they have brackets for these panels. They then proceeded to send me the hangers free of charge. The brackets were pretty straightforward and easy to hang. I couldn't be happier.

After buying a new TV, it's sound comes from the whole screen. The problem is as much sound comes out the back as the front. A loudspeaker would kill all the rear sound by having absorbent material at the rear. I put these directly behind the TV, it killed dead any rear reflections. A bit expensive, but it worked.

Overpriced, and at best moderately effective.

My brand new piano resonates strongly since I fitted in a tight space with three walls surrounding it. The reverb and high notes are not bareable at all in my music ear. Trying those panel out and they worked! I can finally enjoy my new piano!! Highly recommend to players struggles with the resonating sound. Easy install and 3M sticks to the wall with ease and item is lightweight yet felt premium in quality.

With 12 foot high walls and a vaulted ceiling, the sound from our cabin’s living room echoed loudly in the loft. After installing these acoustic panels, there was a noticeable difference, but still echoed. We’d probably benefit from two more sets to get the desired results. Thankfully, the panels themselves are attractive, albeit plain, and we’re looking forward to the aesthetic of mixing gray panels with the black. The panels themselves are heavier than expected, but mounted easily to the walls and the adhesive has held them firmly in place. I don’t know much about sound absorption and decibels. All I needed was a solution to reduce the echo upstairs, and these panels are the way to go.
