US Cargo Control Large Sound Blanket, 96 Inches Long by 80 Inches Wide, Black Sound Dampening Blanket, Durable Woven Cotton/Polyester Blend Material, Machine Washable, 12 Pounds Each, Pallet of 60

My bedroom window is 8' wide by 5' long. The window faces the back of the house, and the neighbor behind me has a noisy pool pump. So, I've done a few things to dampen the sound. This blanket just covers my window leaving only 1" on each side. The better option would have been to use two side-by-side blankets that overlap in the center and that extend onto the wall. Aesthetics wouldn't permit this. So on the window, I have slats, then a blackout liner, then this blanket, then blackout curtains. The difference in sound absorption is noticeable after hanging this blanket to the existing mix.I have a few comments about the installation. For me, this was a two-person job. I hung the grommets on picture-hanging hooks nailed into the stud. First I positioned each side and then worked from the middle out, alternating from one side to the other, smoothing out the stretch. Given this stretch, I had to reposition the hooks on each side afterwards. I measured from the ceiling down to position each hook. The grommets are not evenly spaced. So, if you later decide to hang from the other side, you would need to place the hooks once again. Not fun!The other potential benefit might be insulation of the window. My window faces west and, therefore, gets full sun all afternoon during our 110+ degree summers. The exterior has a solar screen. While it helps, it doesn't do the complete job. I still feel heat on the glass, which is double paned. Hopefully this blanket will help during the upcoming summer.One review said the item smelled and needed to be aired out for a day. I noticed no smell at all.

I hung up 2 of these right over my double pane window and they cut the noise level in half! Now I can sleep through all the dog barking and straight piped Honda civics outside.

I like these.. I don't really know why. I hung them out the walls as sound dampeners and I just like the look and feel over paint despite being much more expensive. They are heavy and thick.There was a slight smell upon opening but after a day we didn't notice it.They have definitely made the room itself quieter with reduced reverb, but I can't say they made a difference with noise reduction into the next room. If you want to improve sound within a room, I think they work fine. If you are trying to reduce sound between rooms I don't think this will make much noticeable difference.

Great size. Nicely manufactured

Thick and heavyHung these on the walls of my rehearsal studio

A mixed bag, depending on your demographics. My experience is that the foams only seem to attenuate incoming sound (make it more localized so you know what to block) but these blankets work to ameliorate the incoming sound (absorb some noise). In other words, it does what it says it does, with a caveat. For apartment dwellers trying to block sound on a connecting wall that seems to be really thin, these may not be the best solution IMO Let me try and explain in my words. Within 6 feet of a blanketed wall, no matter how localized the sound is, the entire blanket absorbs the sound, sort of like a lake with ripples, and appears like a wall of sound. The farther past 6 feet from the blanketed wall you get, the more you can notice that sound is actually being absorbed, and the sound has been dampened significantly. If you put a blanket on an apartment connecting wall, and then place a recliner or bed directly up to the blanketed wall, it may seem like the blanket does nothing at all and perhaps makes the sound worse. HOWEVER. If you are in a house, where neighbors are at least 20 feet away with a high pitch noise maker they mount on their wall (it's marketed as a prank but is always used criminally) these blankets will make a difference. These blankets will not block the sound. Heck, 2-pound MLV may not entirely block it. These 14-pound blankets are only marketed with an NRC, and they actually work as advertised.

Dude, this thing's a total rip-off! They say it's compact, but it's a lie. It's overpriced junk; not thick or compressed at all – you can cut it open and see it's just regular cotton. Noise goes right through it – no sound suppression whatsoever. Not worth your money; save yourself the trouble. Shipping's fast, I'll give them that, but I wouldn't use it to wrap furniture; your stuff will get smashed.

The item is VERY HEAVY, keep that in mind. The size is big & I can cover my whole bed with it. The smell is strange, but I’m sure after one wash it should be good. Definitely need hooks to mount it, Amazon has great options, I suggest garage hooks for the sturdiness. Now to the downfalls, as you can see by the pictures it has minor damages, possibly due to factory manufacturing. Third image shows fabric cut but not trimmed off, there was more but I don’t have time to photograph all of them. So overall, a decent product & does damp out noise the moment it’s opens. Coming from someone who lives near an airport, trust me when I say it does NOT noise cancel, but dampens. Yes, you will still hear those town church bells.UPDATE: I’ve chosen to return the item. As I was hanging the blanket up I found a couple hole loops disfigured by the manufacturer. Making it unable to be hung and used. At first, I was decently satisfied with the minor defects, however, having the loops ineffective makes the whole item unusable, considering movement would need to happen at any time, especially as a part-time or full-time creator. I also tried to upload photos of the loops that were disfigured, but Amazon did not allow me to. I’m not sure if that’s a circumstance just on my end. It’s unfortunate. However, the owner will be receiving it, and will acknowledge my statements as truthfully regardless.Thank you for reading
