Moondream DecibelControl™ 3-in-1 Soundproof Curtain | Noise Reduction | Thermal Insulation | 100% Blackout | Patented Technology | Made in Europe | Grommet | 55" W x 84" L | Brown - Chocolate MC610

I am a professional and measured the sound difference with a professional meter and there was no measurable difference. They are in the mail on their way back to the company.

There’s not much to like when it doesn’t work it doesn’t reduce the noise And it is sold as a soundproof curtain which is miss leading it should be sold as a noise reduction curtain that works at the minimum level

YES, these curtains do indeed significantly reduce noise. The noise reduction power is obviously not going to be as good as a wooden door, but the curtain has about 30% the noise reduction power of one. That's not bad considering it's a curtain. I have tested them extensively, because my sister has a loud 2 year old, and these curtains are helping me immensely. I placed two of them about 6 inches apart in the hallway next to my door. I don't hear the 2 year old playing anymore. When the curtains are open, my room door doesn't have enough power to reduce the noise enough. When I close both curtains, there is a huge difference and I rarely hear anything. If you are using only one curtain by itself, don't expect it to completely block sounds. But it does reduce them, and you can easily test this. Put up the curtain in a hallway, and turn your vacuum cleaner on about a few feet away. Then open and close the curtain and you'll hear the drastic difference. And by using two curtains together in that way, you get almost the same noise reduction of one typical wooden door, or very close. This is impressive because all other curtains I have used produce no significant noise reduction at all. So for all the people who claim this doesn't work, they are either blind or they have very unrealistic expectations, thinking this curtain would somehow reduce all noise to zero. Not even a door will do that.As a tip, if you put these curtains in your hallway, place the curtain rod at a slight angle towards one end, and make sure the curtain sits about one inch off the ground. This will allow the curtain to close all by itself after someone pushes it aside when walking by. I did this myself because my sister would never close the curtain. But by slightly angling the curtain rod, gravity pulls it shut. You have to then use some string or something to tie the other side of the curtain to the end of the curtain rod so that it doesn't also being to slide, but that's easy to do. In the end, you have a very effective sound barrier if you place two of these curtains 6 inches apart in a hallway, and they always remained closed if you angle the curtain rod a bit. I also have one of these in front of my door, which also helps. It's a tight squeeze depending on how much room there is for the curtain rod, but you can usually make it work. You can be very creative with these things and where you place them. You can also use a number of pinching clips to shorten the curtain to any length you want.

I was super excited to receive these because I live in SF where it is extremely noisy and the walls are very thin. I installed them and did a test of the noise with and without the curtains and was extremely disappointed. These do not reduce the noise at all and do not seem very thick either. I am considering returning the product now. Not worth the money.

Did little to none soundproofing

We bought this knowing there is no way for a cloth curtain to be soundproof (and it kills me that they market it like this). However, it knocked down ambient street noise by about a decibel, so there was a slight effect on my noise floor.

What a huge scam!Tested this product with sound level reader, and surprisingly it's not better than a piece of paper in reducing sounds.

I purchased these insulated curtains to try because I live in a NYC apartment that is facing a busy avenue. I needed something to muffle the street noise when it becomes unbearable. I bought these with the expectation of it just muffling the sounds by a decibel, however i was surprised by how well they actually work. Of course it doesn't silence everything but it works well enough for me to take naps during the day.
