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

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.

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 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.

Edit2: Final review 5 stars. New, replacement blanket is in perfect condition. It seems obvious the first one I got was defective and the seller made it right by sending me a replacement. These blankets work great for sound deadening! Very happy with the replacement blanket and with the seller's customer service.Edit: Changing to 3 stars for now due to speedy resolution from seller. I contacted the seller and they are sending me a replacement blanket, after sending pictures they said the one I received must have been one that slipped through their quality control checks. I will report back on how the new blanket compares to the original one and if it is not damaged I will change my review to 5 stars.Original Review: Blanket was delivered wrapped in sealed plastic, but the blanket itself was either highly damaged or clearly used. There are tears, worn areas, and places where the insulation is coming out of tears in the fabric. My theory is that this company is buying USED moving blankets, adding grommets, and re-selling them as NEW sound dampening blankets!Maybe I just got a damaged one? I'm going to contact the company and see what they say, if they provide a solution I'll update this review, otherwise Buyer Beware!The blanket, if it was not clearly used and/or damaged would get 5 stars from me, is is very thick, heavy, and blocks sound from a doorway decently well, but for the high price I should not get something that is damaged or USED!

I have a moving blanket for my vocal booth, but this soundproof blanket is a night-and-day difference. It's much denser than my moving blanket and does a far better job of deadening sound.To give an example: if this soundproof blanket deadened sound 100% (which it doesn’t, but let’s assume it does), a moving blanket would only deaden about 20% in comparison. I haven’t tried other soundproof blankets, so I’m sure more expensive ones would perform even better.If you're looking for soundproofing, don’t waste your money on moving blankets. Get a proper soundproof blanket like this or something even better. I learned my lesson.As for the smell, mine thankfully didn’t have any.
