    Building a "room within a room" for my home theater which is currently under construction. Plan on putting two layers of drywall and a layer of dense vinyl sound barrier material on either the outer or inner wall. I don't want to put it on both for cost and space reasons. Which makes more sense - inner or outer?

    Thanks. Bill

    The best method, it appears would be between the two walls.
    Check out http://www.acoustiblok.com/instal.html
    And click on the reference diagrams at the bottom. Preferably, there should be some space between the barrier and the drywall.
    I decided to put it on the inside wall since I will be adding resilient channels as well (between the vinyl barrier and the drywall).
