Soundproofing Townhome Walls
« on: October 02, 2011, 03:42:29 AM »
Hi all. I wanted some thoughts on a few things I can do to soundproof my 3 level townhome.

My unit is an interior unit attached on both sides, but staggered so not all the walls are connected. I have lived here for 4 years and have never had an issue until recently. They dynamics changed due to new neighbors and an older daugther that moved back the other unit. They are constantly in and out and I hear their car doors slamming and it's super annoying. The daughter pulls in to park in a spot right outside my unit with her music blasting.

One are of concern is the basement. One wall is attached to my neighbors garage. I can hear their car doors slamming and it vibrates in my unit. Never heard that the first two years in the unit. The only thing I can think of is I ripped up the carpeting and installed laminate floors. Perhaps that is allowing more sound? What can I do to eliminate or minimize the noise/vibration.

The second issue in this 3 level townhome is I can hear the car doors slamming in my two upstairs bedrooms. I can also hear muffled voices on occassion from the lot.

It sounds like the most cost-effective option would be Window "Plugs" that right? Is it easy for someone with little "handyman" experience to create?

Lastly, my final issue is with a partially shared bedroom wall. I can hear what I think my be the closet door closing. I have also heard occassional foot steps when my last set of neighbors had a 4 yr old. Now there's an adult in that room and I'm concerned for the future and want to prevent an issue there. Sounds like the 2 layers of drywall with green glue would be a solution?

Ok, for the easy stuff.... window plugs are good for outside noise coming in through windows.
2" foam mat is what is used for window plugs.

When it comes to walls / ceilings it is a bit more complex... for the bedroom 2 layers of drywall and green glue is a good band-aid , however opening the wall and using cotton fiber insulation with MLV will deliver a far greater reduction.

For the basement, this is where I will need far more information in order to make a viable recommendation.
