Saiqiang Blue Acoustic Panels 24 Pack 1 x 12x 12 Inches Sound Proof Foam for Wall Soundproof Noise Cancelling Wedge Studio Foam Panels Sound Absorbing High Density

Bought these so I could be loud in my calls, they work great!

They look extremely thin at first but then they expand as soon as you open them and they work perfecly for a studio, they might have a cut end or 2 but they don't rip easy and they look, and work great to stop echoes. Great value!

Giving it 4 since it didn’t come with any way to attach. Ordered a different color with same company and those did. I’ve made 4 orders now trying to hunt down an adhesive that would work without spending $60 for 48 panels. These are better than any temu tile at the same price

Doesnt block sound

Easy to install inside a 3 " pipe to quiet a Radon removal setup. No fan noise gets back to the house.

Not very high density. But not bad for the price. I used them inside speaker enclosures for a hobby and they worked okay

I ordered 2 of these because I didn't want to run out on this sound-deadening project. The surface area to be covered isn't a simple one since it needs cut panels in order to fit and be most effective. The surprise came when I opened the shipping box and- wondered where they were. (Compressed and in black vacuum packs, almost totally flat and invisible on the bottom of the box.) A plastic wrap around the heavier plastic holding them all so flat took a little time to cut away since I didn't want to damage any of the panels, but after puncturing and then sliding the heavy cover off they began to expand immediately. In only a few hours they were each almost full-thickness and ready to be installed. I used a caulking gun with silicone adhesive (that sticks to ANYTHING) laying them out first and snipping the odd rows to fit. It probably doesn't matter too much it there are small gaps, the sound will still be attenuated. This is a lightweight folding chamber that's large enough to fit over me when I'm sleeping (note: Adequate Ventilation!) because of the noisy fat people upstairs who not only stomp back and forth at all hours but also drop Heavy Objects on the floor - that are like Explosions! (How RUDE!) Ahhhhh! The benefits of not having to listen because there's a solution to excess noise!

Overall these were a great purchase. I used adhesive and put them in the ceiling of my vocal booth. They do come very vacuum sealed and sucked down to just a few inches thick, meaning they'll need to expand before you can use some if not all of them. I've seen people saying they won't expand back to normal. I have found the easiest way to get them back into shape and get rid of some of that chinese factory smell, is to put about a dozen at a time in the clothes dryer on low for 5 minutes and add another 5 as needed until they return to normal. You may have a few edges or in my case, corners that needed a kick in beanbags with a hair dryer or heat gun on lowest setting to get them to expand. It does take keeping the heat on the edge for a few seconds, so don't move it back and forth too fast. You will soon notice that like some people, it will slowly creep back into its proper shape when sufficiently heated. For installation I used 3M Super77 spray adhesive and gave the back of each tile a light coating, 3 at a time. While they were getting tacky, I measured out the approximate area in the booth and gave it a light coating as well. When both surfaces were tacky, it was go time! Keep in mind these will shrink a bit, maybe 3mm, in the first few days, so pack 'em tight to each other to help counter this issue. So far their performance has been as expected. Nothing to complain about here. I would recommend these to anyone who read down to this point in the review. Peace out!

As long as you follow instructions it will puff up and be a good size, Everything is good except some of them had a slight warp on the edges ( unsure if it came like that or if it was cuz of my dryer settings ) but they are good

Great for sound proofing but I ordered 4 packs and they all came separately and took 3 weeks

Very good product and i am very happy with it. I used them for soundproofing my music room.

Une bonne epaisseur
