I found a really good article which breaks it down with pictures and everything. It seems to co-incide with several things that are being said here. In another post, I saw that a good sound level meter would be helpful in testing the issues. Does this information seem correct to address sound issues coming through a wall? Thanks. I got the info formt his website:

Decoupling: Double stud wall insulated with fluffy fiberglass insulation to help with high frequencies.
2nd Best Type of WallWall Type: Damped drywall (Green Glue sandwiched between 1/2" or thicker drywall) to help with resonance, ie. low frequencies
Decoupling: Staggered stud wall insulated with fluffy fiberglass insulation to help with high frequencies.
3rd Best Type of WallWall Type: Damped drywall (Green Glue sandwiched between 1/2" or thicker drywall) to help with resonance, ie. low frequencies
Decoupling: Sound clips insulated with fluffy fiberglass insulation to help with high frequencies.
4rd Best Type of WallWall Type: Damped drywall (Green Glue sandwiched between 1/2" or thicker drywall) to help with resonance, ie. low frequencies
Decoupling: Wood or metal furring channel (not resilient) insulated with fluffy fiberglass insulation to help with high frequencies.
5th Best Type of WallWall Type: Damped drywall (Green Glue sandwiched between 1/2" or thicker drywall) to help with resonance, ie. low frequencies
Decoupling: Resilient channel insulated with fluffy fiberglass insulation to help with high frequencies.
If you want to use conventional drywallBest Type of WallWall Type: Add an extra layer of drywall to one side of the wall and/or use thicker 5/8" thick drywall
Decoupling: Double stud wall insulated with fluffy fiberglass insulation to help with high frequencies.
2nd Best Type of WallWall Type: Add an extra layer of drywall to one side of the wall and/or use thicker 5/8" thick drywall
Decoupling: Modern sound clips like Whisper Clip insulated with fluffy fiberglass insulation
3rd Best Type of WallWall Type: Add an extra layer of drywall to one side of the wall and/or use thicker 5/8" thick drywall
Decoupling: Staggered Studs insulated with fluffy fiberglass insulation
4rd Best Type of WallWall Type: Add an extra layer of drywall to one side of the wall and/or use thicker 5/8" thick drywall
Decoupling: Resilient Channel insulated with fluffy fiberglass insulation
5th Best Type of WallWall Type: Add an extra layer of drywall to one side of the wall and/or use thicker 5/8" thick drywall
Decoupling: Wood or metal furring channel (not resilient) perpendicular to the studs at 24” on-center insulated with fluffy fiberglass insulation
