TONOR4 PCS Large Acoustic Panel, 23.6″ * 11.8″ * 2.36″ 3D Fiberglass Sound Proof Panel with Full Self-Adhesive, Decorative Echo Absorbing Wall Panel, for Studio, Living Room, Home, Office, Beige

These soundproof panels are exactly what I was hoping for! They’re incredibly thick, substantial, and feel high-quality right out of the box. I’m planning to mount them on the ceiling in our recording studio, and I’m confident they’ll make a big difference in sound clarity.The sound absorption on these is impressive with an NRC of 0.95, which means they’re great at reducing echo and absorbing noise. The panels are wrapped in a high-quality fabric that not only looks sleek but also scatters sound effectively. They’re built with safe materials—100% polyester fabric and a glass fiber core, flame-resistant, non-toxic, and odorless—so I feel comfortable installing them indoors.Installation should be a breeze with the self-adhesive backing. I also really appreciate the minimalist, professional look; they’ll blend in perfectly with the studio decor.All in all, these are some of the best soundproof panels I’ve come across—super high-quality, functional, and well-designed. If you’re looking to improve sound quality in your space, I highly recommend these!

I got these panels to supplement the existing panels that I already have in my music / guitar room (or...my husband's music/guitar room)Currently have no complaints. They were nice and heavy...solid construction that seems like it will hold up well for a long time...but also easy to hang and install.They definitely muffle the noise...which was my main reason for getting them!

I have maybe 40 sound absorbers on my ceiling, recently bought 2 of the 4 pack 36" and installed a 4 pack so far. One thing I noticed right away was the smell, it's a very noxious smell. The item details say this is E1, that's great, but everything else is E0 with no smell. The finish and adhesive on this is much higher quality then anything else. This would be perfect if it were E0 fiberglass.

These are great panels for the office or studio. They will help deaden unwanted sound reflection. My only complaint is that they have no built-in mounting brackets, and I've tried to use screw and nail saw mounts, but they won't stay secure. Probably going to have to use command strips.

I am really happy with these sound panels. They are made very sturdy and they also do a good job of what I'm needing in my home recording space. They measure exactly as the listing is showing and they also are at a good thickness that my walls can handle without too much headache.They are also really well made and I love that they come in a four pack.I can recommend this product.

I help run a small community radio station and we recently had a bit of a problem with a new transmitter unit. It sits outside the studio, but it makes a heck of a noise. Enough noise that it leaks into the studio and is audible on-air. Obviously, this isn't acceptable and we tired a few things to muffle it, but to no avail. Even the conventional foam sound-absorbing tiles didn't do enough - they removed some of the low frequency noise, but did little for the piercing higher frequencies. So I was keen to try these.They're made of fibreglass and are quite substantial. With some careful positioning, we were able to cut down the noise substantially to the point where it doesn't reach the studio at all. Nice. The great thing about these is that they don't look like acoustic panels - they look like decorations. So we've been able to rather subtly cover up for an annoying noise whilst keeping the place looking nice.I'm looking to get some of these for home as well. I often record bits for the radio from home, so it'd be nice to treat my room without having ugly standard panels there.They're self-adhesive so you don't need any tools to stick them up. They're heavier than you might expect, but that's not a problem as the adhesive covers the whole of the back and is very strong. They're quite thick too. You might feel a little anxious when you first stick them up (I know I did), but the adhesive is well-suited to the task. I would advise careful experimentation before committing to position as they're not easy to remove.A very strong recommendation from me. Very effective and quite discrete, despite the size.

These panels feel good and solid, but not heavy. The fabric covering is neat and fits in well in my garden room and the large self adhesive panels on the back made installation a breeze. They really cut down on the harsher elements of the room and make the recordings my wife makes in there a lot cleaner.
