Do Soundproof Curtains Actually Work? FULL SOUND TEST!

Soundproofing curtains is not something that would actually soundproof a window. They should be called sound deadening curtains because they absorb the sound in the room and can also absorb outside noise but they aren't not noise blocking curtains.
In this video I did a sound test of a triple layer sound deadening curtain. They are also called blackout curtains because the middle layer is a thicker black felt that blocs the sunlight. It also helps black a little bit of noise, you will be able to see the before and after sound test with my decibel meter for these so called sound proof curtains.

The hero we didn’t know we needed😭😂

[@earthenscience]

He babbles for minutes about trivia such as how he didn't order the right size of curtains. Then he botches the experiment by changing the sound effect before testing the new curtains. Right after he notices a strange phenomenon of the other curtains increasing the decibelage for no apparent reason, but he doesn't explore that. Nor does he test other brands or styles of soundproof curtains. I think it is partially on KZbin though for encouraging people to make 10 minute videos instead of shorter ones.

[@jimbrown563]

4 additional points ..... 1) Your Noise Maker Box can not possibly create any frequency below ~100hz with a tiny ~2 inch speaker, therefore, this testing method is rather limited in scope. Traffic noise, especially large trucks, can produce extremely low frequencies, which these Curtains will not have very much effect on because they are relatively light weight, and lots of MASS is needed for low frequencies. 2) You did not mention the fact that these Curtains will also absorb a lot of noise originating INSIDE the room, as well as reflections/resonances/echos in the room. 3) Regarding installation and effectiveness ........ The Curtain should be ordered in a width that is 2 to 4 times WIDER than the window opening. The curtain should NOT be "flat" when closed, but should remain "convoluted" into an "S" shape, all the way across the window, even when completely covering the entire window opening. This will increase the total MASS/WEIGHT, and THICKNESS of the Curtain, and substantially increase its effectiveness. 4) If the Felt can be removed for washing, then it should also be possible to add a sheet of "Mass-Loaded-Vinyl" INSIDE the Curtain. This would increase its noise absorbing effectiveness substantially. . .

[@soundproofguide]

Those are all excellent points! I will certainly mention the MLV inside on a future video! Thanks for the tips!

[@jimbrown563]

@@Skysdalimit247 Move at least ~5 miles away from any Train Tracks. You may still faintly hear the Train's Horns, but at least the ground won't shake as much. Curtains will make zero difference to Train noise. A Concrete Building with Triple-Pane Glass will stop most of the low frequencies from a Train. . .

Can u do more of apartment owners and what we can do on stopping noise to go throw or coming in I was thinking of just getting using a sound Curtains the wall i share with and maybe behind it the foam squares i know you said on ur other videos it dont block the sound of coming in or out but I felt that its on of thing I can do to my apartment so that its two way of blocking something the square foam then the Curtains I was also thinking of getting dry wall and standard up without screwing anything to the walls or gluing anything Just maybe having some putty to keep both of them attached to each other

[@Stashword]

3 dB reduction corresponds to **half** the noise. Decibels use a logarithmic scale.

[@corbinslaymaker3346]

@Jingcheng Ma it is when you consider reflections and the sounds ability to pass thru material (thru walls into other rooms and/or neighbors if you live in an apartment)

[@jaredcook3757]

That is in terms of pure sound energy. In terms of perceived volume by humans, 10dB is the rule of thumb for half. But then we need to talk about what frequencies? Bass frequencies, which are the biggest problem, are likely not reduced by these curtains by even 1 dB. OK for chirping birds. However, I will agree that 3dB is not insignificant as part of a plan for general noise reduction. It just shouldn't be the only thing you do.

So I was thinking maybe getting a soundproofing curtain to use over the door? In terms of bass, yes you can still feel it slightly and I know it’s going to be very difficult to stop bass. Also now I can hear more of an echo so I’ve got some foam panels to put on the wall.
