Apartment floorplan diagram and sound questions
« on: May 14, 2011, 01:19:53 AM »
I'm sort of cross-posting this from another forums but I figured this would be better.

Here is my small apt- ~400 sq ft, built in the 1960s, so expect typical drywall and lack of sound insulation.

I've had trouble with the sound transmission through the shared kitchen wall. I thought about putting egg crate "sound proofing" foam over the entire kitchen shared wall (by the fan) but then as I read on at this site that isn't enough to do the trick. So I thought about getting masonite sheets and covering those in foam, or putting some MLV sheets first, then foam on top. It gets expensive though because I'm covering roughly an 8x8 wall. I would drill 4 screw holes in each panel and mount them over the entire wall.

There's a 1000 character limit (?) so I'm posting the other half of my thread here.

As of now, I have a small entertainment stand (TV & speakers) on the wall labled "C" but previously I have had everything on wall "A". The floors are synthetic hardwood and the ceilings are acoustic sprayed, 8ft high. Unfortunately the walls are thin (I don't blast my music but you can hear EVERYTHING like the other person scraping their dinner plate, talking on the phone, TV, ugh) so I know that the sound at reasonable levels creeps through the walls. The bathroom wall is an outside wall same for balcony. Wall A goes to a hallway staircase to the other apartment and sound travels through that wall easily too for some reason.

Your idea will be a waste of efforts, if you want to get a quality reduction based on the money invested you will need to soundproof kitchen wall entirely for transmission through the wall and wall A on your diagram.

You will need to remove existing drywall and do a sound control wall inside the assembly to get good results.

Ahh, that's too bad. Unfortunately the property management won't do anything about it. I e-mailed and told them the details and they said they can't do anything and said maybe I'll get neighbors that are quiet. That's not the problem though.  I can't afford to put up all new drywall :-\ That would also involve removing the cabinetry and the wall mount microwave plus downtime from both myself and the neighbor.

Thank you Randy for your input.
