Soundproofing Home Theater with a Party Wall

I live in a townhouse and I am trying to achieve optimal soundproof reduction for my home theater which shares a party wall. Often, I can hear the neighbors running up and down the steps (structure-born noise) and loud music.

I plan on doing the following:

1) 1lb mass loaded vinyl (with soundproof sealant)
2) Resilient channel (RSIC-1)
3) Roxul insulation (any advice on which one?)
4) Putty pads around electrical outlets
4) 3/4 inch drywall (with soundproof sealant)

Did I miss anything? Any advice on how I can further soundproof the wall?

While your plan might help a little , don't expect big changes . I did insulation, putty pads , MLV,5/8" OSB and 2 layers of 5/8" drywall with a green glue competitor between all layers and it helped , just not much.Without my subwoofer on I may be able to go 10% louder on my system before it bothers my neighbor . Problem being flanking paths , 2 walls at right angles on either side of the wall I treated , floor and ceiling . The wall I did isn't load bearing , so it was built on top of the shared subfloor so theres a direct flanking path from my space to my neighbor .

I don't know if the resilient channel will make a difference since I didn't use it , but my gut says no because of all the flanking , but if you have a way to minimize flanking paths either now or in the future then It may be a good idea.

yes it was. Flierguy the MLV is no better than adding an extra layer of drywall so compare the cost. Resilient channel is very prone to installation errors you may want to go with A237 clips and 7/8 furring channel. You should read this counter argument before installing it points out all the things to avoid. https://docs.google.com/viewer?url=h...8.pdf&pdf=true

Thanks for the advice - big difference between RSIC-1 and A237 clips?
