Okay While they do dampen some noise, they're not effective at blocking out low frequency noises. The website notes that this, but I thought I'd give it a try. Blue color is attractive and they look good. Installation a bit confusing because the velcro is inset from the edges. Took longer than expected to receive the blinds. Overall, they're okay, just not very effective at fixing my particular issue.

Works as advertised! I live in downtown LA and also have an east facing apartment. the traffic noise can get kind of loud and at night can be disruptive. I found Residential Acoustics online searching for solutions and I took a chance on them. Not only is any sound at all barely even noticeable, the curtains also completely block out all the sunlight that used to pour into the bedroom, making it much easier to stay asleep until its actually time to wake up.

Noticeable noise reduction The curtain is helpful in reducing outdoor noise as well as early morning light. It's heavy, but the hooks provided make mounting straightforward. Raising the curtain is more work than a conventional curtain, but the straps work well. I'm a satisfied customer.

They Work Really Well ! I usually do not write reviews, but was so happy and surprised at the job these curtains did to block noise. We live in some houses that literally a 5 feet from your neighbors and right next to the freeway... So needless to say it was hard to sleep without hearing my neighbors outside or the rush hour traffic. I ordered enough to cover the bedroom windows and not it is literally almost silent in my master bedroom. As a light sleeper and someone who wakes up from talking or traffic, i would recommend these without a second thought!

The curtain is not effective The curtain does not performed as advertised. The noise reduction effect is minimum. Customer service did not follow up my questions until I emailed them the second time. Even then not all my concerns were addressed. The curtain can be functional as a blackout or thermal curtain, but not so much as an acoustic curtain.
