Knightsacoustic 52 Pack Acoustic Foam Panels 1 X 12 X 12 Inches Sound Proof Foam Panels for Walls High Density Studio Wedge Soundproof Wall Panels Sound Proofing Acoustic Panels1

Works better than I expected. However, I didn't purchase enough. I also researched different products. Smell was one of important factor.

I bought this to reduce outside noise pollution in my old apartment with poor window and door seals. I was skeptical and not expecting much, but I had to try something. The foam itself seems high quality and is very thick. Yes it took some time to fully expand, but it did expand. No the smell isn't great, but that's how foam smells and it goes away quickly. The adhesive pads included worked very well on every surface I tried with no pretreatment. I tried them on glass, metal, and painted surfaces. I was able to cover my entire bedroom window, the frame of my front door, and the edges of my balcony door where there were gaps. It has reduced the sound inside noticably, especially in the bedroom where I used the most foam. On my front door I used a staple gun to ensure the pads won't come off with opening and closing the door. Now the only sounds that come through are the horn of the nearby train, and the annoying straight piped pickup trucks everyone seems to have in my area. But both are still reduced enough to be livable now. It's nice to finally relax in my own home. I'm strongly considering buying more for my home office and the rest of my front door, it was worth the money spent so far.

The is a great buy. You get a LoT of pieces for the price and. Sb definitely cover a wall. They are very thin though. So bot sure you’ll get studio quality unless you cover all your walls.

Minus one star for this product being advertised as SOUND PROOFING panels, and using this term synonymously with ACOUSTIC panels in their product description. They are not the same thing. These provide next to NO value as sound proofing because that's not what they're really meant for, and is the source of most negative reviews for these and many similar types of panels on Amazon. They are ACOUSTIC panels, meant to remove unwanted echo and reverberation from a recording space, and NOT meant to insulate sound. Do not buy these if you are actually looking for sound proofing.Minus another star for how THIN these panels are. I bought some acoustic panels a few years ago, and wanted to add some additional panels to the room, and these are literally half as thick as the ones I bought previously. I think this is essentially "shrinkflation" for foam products generally, as every other acoustic panel I looked at had this same sort of complaint in the reviews.Other than that, these still work well enough for their intended use - cover your walls with them, and it will still remove any echo or reverb in the room just fine.These come in a vacuum sealed pack like most other similar panels, however these also come in a box, which prevented the panels from getting banged up during shipping - I had no issues with smashed corners or edges on any of the panels when they re-inflated. They also popped back to full size almost immediately, no need to dunk them in water or wait days for them to breathe, they were ready to install right after removing them from the packaging. They also didn't leave a strong chemical smell in the room for days, like other similar panels I have bought in the past. I also appreciated that they were a uniform size, I had real problems with my previous panels all being slightly different dimensions and making it really hard to cover the walls symmetrically. Do note these do NOT come with any way to actually stick them to the wall - I just used a staple gun with black staples though, and it looks great!

Saw some mixed reviews, especially about the quality of the stickers, but these work great. Easy to install and have stayed up without any issues on my wall for months now. It's done a good job of dampening sound, especially for the price.

You get what you pay for. Cheap and flimsy. I would haven you at least a 4 but Amazon gets the 1.

Great item sound proofed my bedroom now I sleep like a God !!

Great quality, a bit expensive, but if you are serious about sound proofing - YOU NEED TO BUY THESE.
