TroyStudio Thickened Acoustic Panels, 16 x 12 x 0.5 Inches Pack of 6 Felt Wall Decor Tiles Sound Absorbing Board, Noise Reverb Echo Dampening Soundproof Padding for Door Music Recording Home Studio

They seem thick and good quality, have almost no smell at all (have to put nose right up to it to even know you're smelling something). I like that there's no adhesive since I can use smaller, wall-friendly adhesive strips as opposed to covering a large surface area that would be hard to clean which makes installation and removal easy. I've bought one 6 pack so far. It has made a relatively small difference at sound penetration outside of the room I installed them in, however what I found most effective was placing one under my laptop where the speaker are, and the sound that comes out of them is significantly less piercing but still enjoyable. The gray color is very neutral and goes along with a lot of different paints/color schemes. What is most noticeable after installation is inside the room there is no echo when talking in the corner that they are installed, whereas the same building has a strong echo when talking in the adjacent hallway where they are not installed. At this time there is a very significant door leak in the room I installed them in so it is difficult to fully assess the soundproofing effect, so take any less effectiveness in my review with a grain of salt. It did seem to dampen the sound well when placed under the laptop and I'd feel better about recording in this room now.

These are really nicely made and work great for catching first reflection points from my speakers on my desk. I also have one behind each of the speakers on my desk attached to the wall. They look good and work good.

On the one hand, these work well for what they’re intended to do. By ear, they reduce room reverb as least as well as acoustic wedge foam. I’d be harder on the reviews complaining about soundproofing effectiveness (this is probably not the best tool for that), if the description didn’t include the word “soundproofing”. They’re pretty rigid and command strips stick well directly, both of which make them less work to hang than foam. They’re about three times heavier, with no noticeable odor. White acoustic foam is almost impossible to find, and the one source I’ve seen wasn’t fire retardant. This is at least white-ish, and fire rated. On the other hand, they’re not 16x12. They’re very precisely cut to 15 3/4” x 11 7/8”. This doesn’t really affect coverage, but does make placing them by measurement harder and the error can visibly add up. The ‘white’ color is a very light grey with a blue cast, I’m okay with them on a white ceiling but wouldn’t put them on a white wall. Picture attached showing both measurement and comparison with white (under ~2800K light). Still giving them four stars because they work well (I ordered more after trying them out), but I wish the description was more accurate especially the measurement.

I used these 1/2" thick felt panels to tone down the booming sound from the 6.5" subwoofer of my DIY computer sound system. (I had placed it in the less than ideal alcove space beneath the desk in my small, carpeted home office.) Strategically attaching halves of a few of the 12 x 16 panels to the walls and ceiling of the 'woofer cave' (with either 3/4" long washer head screws or 1" square velcro tabs) helps to absorb some of the reflected excess bass. Together with a 9 band equalizer, they were able to make my poorly placed subwoofer's sound tighter, less flabby and much improved. They can be cut neatly with a few repeated slices made by a sharp utility knife guided by a straight edge. The black color I selected makes them visually disappear down there, but I can hear the improvement.

I am using these to dampen the sound coming from my laundry. To be fair, I have not installed them in the most intelligent way due to size constraints, but they are still making a noticeable difference. Look nice too.

These panels are as listed but cutting them down to a needed size makes a lot mess and the material itself is falling a part.

These are great and easy to mount and use. They reduce reflections and echoing, especially in my office space

I bought 2 pack to fill in the gap of my windows and they really block the noise coming through from my neighbor...highly recommend!

Used on hollow bedroom door and made noticeable difference.

Since I'm a musician, I soundproofed my room with those, and they are very dense and block the sound out very well. They are also great for sound treatment.

Excellent! Dense foam in smaller pieces that can be hung on walls. Feels similar to cardboard, easy to screw in hanging hardware, light enough for 3M hooks. The colour is available in natural beige which is pretty hard to find.

great for my office, i use it as a cork board for pinning paperwork. Also blends in with decor.

Add adhesive squares to the back for easier installation.
