At Casa Verde, our duplex units are separated vertically by two 2x4 walls, with 
unobstructed 
open space between them from attic to basement.  

Works great.  Next to us is a family with two children, one of which studied 
French horn,  and 
two dogs.  We never hear a thing.  

The design was done by Synergy Design, Matt Worswick.
