Yeah, I will add another layer of drywall to the ceiling of my listening room some day and plan on using greenglue.

My stupid builder (said he'd done sound rooms) wouldn't follow the drawings and use gauge metal "Z" strips to attach the ceiling drywall.  But my bad was installing six recessed can fixtures in the ceiling.  And unfortunately the kitchen/mud room are above my room.  But the good news is I do lots of listening at 5 AM when no one else is up to wash dishes or clothes.

Otherwise the room is well isolated physically (double staggered insulated interior stud walls to adjoining storage rooms, two outside basement walls, insulated exterior fiberglass door with weather stripping, and lined fiberglass supply air duct).

greg,  move to long beach, washington!  no one here has ever started a truck or made any other kind of noise.  don pettit

ya know, we don't always get to choose where we live and what we DONT know about our new abode. One thing I do is make a little noise in the back yard and see how many dogs reply. I try to ask about traffic and take in the neighborhood to see what surrounds me. The house that I bought here is relatively quiet, there will always be some noise, neccesary or not. Headphones are an option for some, but I am not, as of yet, a convert. Good luck in finding the right place for you...
