Sound isolation/blocking

Hi lain, I have a problem. It's loud as fuarrrk at night where I live, mostly low-frequency noise from machinery. My room has one window which barely blocks any noise at all. I need to fix this situation so I can get a good night's sleep without using earplugs, which hurt my ears. >use headphones I tried this, but since I almost always sleep with my head on its side it was uncomfortable. >just change the window to a better one I'm a renter and I'll probably move next year. >hang up thick curtains I did, it didn't help much probably because the curtain-hanger thing is about 5 inches from the wall and I couldn't find any proper blackout curtains. Currently my plan is to build a thin wooden box that covers the window, with an opening on the bottom for air to get through, and cover the inside of the box with acoustic foam. There are some potential problems I've identified: 1) I'm not sure whether I want "sound blocking foam" or "sound absorbing foam". I want the sound to hit the walls of the box and not leave. 2) even if I get the right kind of foam, enough sound might escape through the hole in the box to make the whole exercise pointless anyway. Any lain with experience in soundproofing/acoustics in general got some advice?

oh and I forgot to mention, of course the box will be removable so I can have natural light in my room during the day.

>>8073 You should take into consideration the frequencies, you say it's "mostly low-frequency noise". How low exactly? If they are very low your acoustic foam box would probably be useless and there's not much you can do. But I assume it's actually medium frequencies that bother you if it's machinery. There are actual soundproof curtains, you should look into those.

As the other anon already stated, low frequency noises are very difficult to eliminate without some major work to the building itself. Also why there are machinery running at night? Do you live near a factory?

I do audio and acoustics professionally. your problem will not go away with acoustic panels or anything like that. best thing to do is to double up on any/all windows by turning them into double-paned windows. anything further than this will be major reconstruction & probably not worth it. blackout curtains and double paned windows are your best bet.

>>8075 >>8076 The building across the street has what sounds like a huge air conditioner and they never turn it off. >>8078 Hmm, I can't hang up blackout curtains close to the window. Maybe I should tape them onto the window?

>>8079 Not the guy you're responding to but if you're getting the blackout curtains regardless you might as well try taping them to the wall.

I'm thinking you could take pool noodles cut to the width of your window to snuggly fit and have them tied together and pushed right against the window pane so it reduces the space it has to move. May quieten it down some by absorbing and deflecting some of the sound. Im not sure if filling the holes of the tubes with spray foam after they are tied together will help make it better or make it less effective. This will make it easy to keep it in place with no special made mounting system required. I don't know what colour may be best because Im not sure if black against the window would get hot enough to melt or not depends on where you live. Pool noodles are made of polyurethane which is same material acoustic foam is made of but I assume it's density is different. I don't think pool noodles are treated with fire retardant so may want to consider covering it with fire retardant fabric. Also put handles to make it easier to pull out from the window. Bonus this design can be rolled up for storage or just shoved under your bed.

I have tinnitus, maybe some sort of auditory hallucination, and screaming women. https://f-droid.org/packages/com.github.ashutoshgngwr.noice/ https://www.f-droid.org/en/packages/com.cliambrown.easynoise/ https://asoftmurmur.com/

>>8088 that soykaf never works for me, just adds to the noise.
