I bought a duplex and I’d like to do my best to make sure I don’t hear my neighbors (much). This doesn’t need to be recording studio quality. I just don’t want to be bothered by neighbors, and I don’t them to be bothered by me when I watch a movie at 10pm. I’m remodeling and we have to build a 2×4 stud wall in front of the wall that divides the two sides. So I am going to try to “sound proof” it against movie nights while keeping costs manageable.
I can do the double wall, air gap and rock-wool method (cost $4 a square foot) and have money to spare. I’m not sure I can afford the 4″ sandwich of MLV and MDF (cost $26 per square foot). Is there something in-between?
Lots of details in the next post.
Lots of details below:
Primary Structure:
===============================
The center wall is 4″ structural clay tile with plaster on both sides.
The dividing wall is very similar to what is pictured here:

This is all what separates the two sides. The main living rooms all share this dividing wall.
Previous Plan: $3.95 a square foot
===============================
I was going to do the following system which is well within my budget.
Dividing wall Treatment:
* Structural Clay tile
* 1″ Micro-air by John’s Manvile (similar to Corning 703 but significantly cheaper)
* 1-2″ air gap
* 2×4 stud filled with Rockwool Safe and Sound
* Two layers of 5/8 Type X drywall
Living room shelves, cabinets and a faux fireplace will be mounted to this secondary wall so I’m not sure resilient channel is a good idea.
Ceiling Treatment:
* 10″ joists filled with Owens Corning R-30 Kraft-faced insulation batts
* 2 layers of drywall 6″ from dividing wall.. set between joists
Floor treatment:
* Sand filled Cinder blocks in crawl space 9″ from dividing wall that sits on cinder blocks.
* 10″ joists filled with Owens Corning R-30 Kraft-faced insulation batts
Current Plan ???

After seeing your videos
I’ve considering going an alternative approach. I love the idea of your MDF and MVL sandwich, but that would cost me $25.34 per square foot of wall. Labor costs would likely be significantly higher. And I’m guessing this is just the start.
Is there a budget version of this?
