It would be nice to have curtains that absorb street noise.
Some custom curtain tailors offer a fabric that claims to be soundproof. It’s a little pricey. Not absurdly pricey, but it’s also a bit hard to be confident that such thin fabrics can absorb much sound (they claim 20%).
I would prefer to try hacks. I’ve heard that thick furniture moving pads absorb sound well. I’ve also heard that fiberous fabrics can be effective. For the moment, I probably want to pass on edgy ideas like egg cartons. Maybe later on those. What fabrics are decent for reducing sound? Specifically, I’m wondering about carpets or painter’s drop cloths. Not the simple white canvas drop cloths, but the thicker drop cloths may out of recycled fabrics.
I would think two thinner curtains would be more effective than the same width thick curtain, since the decoupling would hinder the sound transfer? Obviously that said, two thick curtains would be best.
There’s a few things at play with noise, and unfortunately there’s no easy answer to your issue.
Easiest and best bang-for-buck: seal your windows up tight. If there’s little gaps for vents, the window doesn’t close tight, or things like that, they will leak noise.
Most effective: replace windows with solid frames or insulation packed extrusions, double glazing using laminated glass, and make the inside pane a soundstop type of glass. Make sure any opening windows have seals.
The curtains probably help with some very high pitched sounds, and there may also be a placebo effect at play, but they’re going to do bugger all I’m afraid. Noise is just vibrating mass, and it’s harder to transmit vibrations through dense mass. So yes, a curtain is better than nothing, but relative to your glass and walls it’s closer to air.
If noise is an issue for sleeping, the very best thing to do before shelling out loads of money on snake oil curtains is to try a few different ear plugs.
A word of advice: if your household has a gravity-centered airflow, please do NOT block all small gaps, else you might develop nasty air quality-related problems later on
I spent many years trying to sound insulate band and recording rooms on the cheap. I'm not an engineer but from my experience you need mass to stop street noise, which has a lot of low frequency power. No amount of foam or fluffy fabric will make a noticeable difference. Save your money on the 'soundproof' fabrics, they're no better than furniture pads, which can help a little but just aren't dense enough to stop much bass. Best I've found for windows is particle board with chunks of tire rubber nailed on. But you probably don't want to board up your windows so that's probably not a good solution for you
I always wanted to find a heavy sheet of rubber to see if that worked but never found anything affordable I could repurpose. Also wonder if heavy muslin dipped in some kind of rubber material might do anything, but never tried that either. Maybe something like those flaps they use in commercial coolers, those are pretty dense, but a sheet. Sorry no specific recommendations for your case but keep a look out for any dense material you could fashion into a curtain or window cover.
But also just check around your windows if it they need any sealing. A tiny opening can transmit a lot more sound than you think.
Right, no "soundproof" curtain will absorb low frequency noise (which street noise unfortunately to a large extend consists of), regardless what ads are trying to sell you. Heavy curtains can absorb high and mid range frequencies quite well and professional acoustic curtains made of heavy (≥500 g/m²) Molton or Calmuc are the best you could get (the cloth costs about 10-15 €/m²), but if honest producers will tell you they won't help against low frequency noise. Anyway, if your windows aren't too large you could try that for a few bucks..
The best bet are new insulated vacuum triple glass windows that aren't cheap at all.
If that is the case, there are also fresh air thingies that are mounted on the wall and have a tube outside but block any sound from outside. Useful when having a bedroom next to a busy road.
Any idea what search terms I can use to find these? Any anchor to kick off my search would be great, image, product page, whatever. I did some searches based on what you wrote and cant find it.
Sound absorbing materials with some space between them will work best, so if you go with curtains you'll want to get the double curtain rod to put in two sets. The space between the material helps reduce the transfer of sound energy.
White noise machines do wonders for killing external noise, but then that's all you hear. Similar to running a loud fan, I can't hear anything when my fan is running.
@CCatMan I appreciate the advice. So this kind of answers one of my questions. I wondered if I take a painter’s drop cloth in matching dimensions to the curtain and attach it, would that be much different than if I double the size of the drop cloth and attach it with deliberate folds (like pleated pants). What you said somewhat implies that It would help to use double the size of drop cloth and force some deliberate folds which would create an air gap with the curtain.
I’m most interested in a cheap option so the paragraph on “Industrial Blankets” caught my attention. But it didn’t give much detail or mention how carpet fairs in comparison.
As an experiment, I took mattress someone threw out and pulled the memory foam-like pad out, and stuffed that into my window, then hung a cheap normal blackout curtain with a drop cloth safety pinned onto that, then i have a thermal curtain hanging on a 2nd support track. It seems to work well although I’ve not tried it on a noisey night. Weekend is coming so maybe I’ll have a better idea next week.
Sound insulation and sound absorbtion are two very different things.
Egg cartons are a myth. They do nothing for sound and only create a fire hazard.
Professionel recording rooms might have egg carton shaped foam to absorb sound instead of reflecting it. It has nothing to do with sound insulation. It does not stop the sound. It only stops the sound from reflecting, so that he microphone gets a clear signal without reverb. You can still hear the sound everywhere inside and outside the recording room.
To insulate your ears from sound, you use ear plugs.
Similarly, to insulate your apartment from sound, you basically need earplugs for your windows.
I live next to a bridge with heavy traffic, a river, and train tracks on either side of said river. Thankfully the train only comes by once or twice a day on our side, but constantly over on the other one.
I got used to the noise relatively quickly after moving in, like maybe a month or two. I'm used to city noise though.
That being said, my eventual plan is to get some heavy wooden window shutters. I figure I can close them up in the colder months, and it should block some noise out. I do keep the windows open in the summer though, no A/C here.
