Possible to sound proof this cheaply?
« on: December 22, 2014, 09:02:47 AM »
The studio apartment I'm currently living in has a weak hollow door and windows like pic related(pic is mirrored, sorry couldn't find other). One upper window grill is on the outside. Now I've put some blankets but I can easily hear conversations outside even with white noise. The rent here is a bit higher and only reason to live here is it's nearer to my mother's.  I don't want to spend much money thought.. Something like sealing open ways and attaching heavy cotton blankets(their cheap) to the doors and windows with adhesive/ply etc. The wall is pretty hollow though. My goal here is not complete soundproofing but not having normal conversations outside audible. Having trouble working here due to all the noise.

What's minimum I'd have to spend? Or I'm thinking of moving to another home with thicker walls, double door and seal the door openings. I don't live in US btw. Thanks :)

The hollow door would need to be replaced with a solid core door..only way to get a cost effective reduction. plus you have to seal it air tight.
Now for the walls, you will have to double the weight of the wall just to see a 5db drop..

Sorry for the late post. I can get how to reduce sound from the door but main problem is the window on the top. It opens by rotating vertically and is a bit loose. I don't need light from it. Would it be enough if I seal it and put some stuff on it. Though I think it'd cost too much.

As for the wall the reduction is 50db with a single layer of brick right?

Also if I'm putting weight on a window or proofing a door, is it necessary for all the parts to be heavy or is it fine if some parts are lighter but covered?

Thanks!

OKAY Now I've done some research..

So I'm thinking of several options:
For windows(which are made of fibreglass it seems)
1)Layer of sheetrock
2) Two layers of sheetrock and fibreglass insulation in between.

For the door, I'll probably have to get it made to be cost effective.:
1)Solid wood door
2)Hollow with fibreglass inside
3)Add sheetrock and fibreglass to existing door and cover any gaps

Currently, I can hear normal conversations outside so I'll assume I have STC rating under 20. So I want to get it up to around 35-40. But I don't want to spend too much and the changes should be reversible.

for your window, you need to create what you would see on a commercial airplane..
mass / gap / mass .... existing window / 2" or greater air space / 3/8" plexi glass.

as for the door ...replace it with the solid core door ..best bang for buck and use the door seal kit
