Rhino Acoustic Absorption Panel 16" x 12" x 0.4" NRC Sound Proof Padding for Echo Bass Isolation Dark Gray 6 Pieces Beveled Edge for Wall Decoration and Acoustic Treatment

My carpeted office has a lot of echo when I partake in conferencing calls. I bought a heap of these (6 boxes) after reading good things about them.Although the echo has reduced, it is only slight and helps very little. I'd imagine no better than the flimsy foam panels you can buy

I bought these to reduce the music and bass noise coming from my noisy neighbor. I do realize that these are more meant for the room generating the sound, but unfortunately I can only just work with my apartment.Before, the sound from the bass was so loud that it was hurting my ears. I could deal with the annoying sound, but the pain was not okay. I bought 3 packs of these and tiled them on the wall. I first felt the wall when my neighbors were playing music and noted which areas had the strongest vibration. Then I tiled them.I would say overall it was about a 30%-40% sound reduction for me. The bass no longer hurts my ears and is just annoying, so that was enough for me. They are expensive, so if a 30% sound reduction is that worth it to you, then go for it.

A little more cost than similar tiles but the RHINO tiles seem to be the most consistent ones (shape, color, etc) sold on Amazon. Pretty sure all of these tiles are made in China so it is important to find good quality ones that you can trust. I installed these using some 2" tee shaped (wig) pins poked through at each corner and into the drywall. Had to cut a few pins shorter where wall studs were located, easy though. I tried shorter tee pins but those were too thin and bent easily. The tee pins worked better than adhesive and probably less damaging to the wall if removed.My design needed strait continuous rows on room walls. It was easy once I had a level strait line set up for reference. Laid down the first row then used that row to guide the rest. If you were installing using a random pattern then there may be more measuring needed. In this room I needed to dampen noise movement from one side to another. A few rows of these tiles on both sides dampened enough that I could call it a success. Looks pretty nice too. Was already well aware that these are not magical noise cancelling items. Having the correct expectation is key to your satisfaction using these tiles.The only complaint I have is on Amazon. They ship these as "in a box that reveals what is inside" but recently removed the "ship inside a box" option (even if other items in the same order). So this loose package can get corner dented during shipping. Resulting in dents that transfer onto the corners of the tiles inside. Sometimes it is minor enough and look okay installed. Other times it looks bad and just needs to be sent back for new ones.I mean seriously Amazon...you're getting pretty lazy lately.

I liked the idea of these and they may have absorbed and blocked outside sound when they stuck up. But no matter how much tape I put on them, using only the recommended two-sided Scotch tape, they would not stay on the wall. I kept buying more tape and had to re-secure these every day. I went away on a trip and came back and found every panel on the floor in a pile. What's the point?

My furnace noise reduced in half based on how it sounds like (not precise measure with tools)
