So you want to hang a massive panel on the door?

So isolation is a goal? If so, you would want the ceiling decoupled to create a spring system. This is different from a suspended system.

OK so a beefed up door is the goal. Any chance sound could enter the ceiling and simply go over (flank) the walls?

 

[Ted White]

No problem. I hope you don't mind the questions. You'd like to meet your goals without doing / spending what's unnecessary.

Having a super massive wall is a great starting point, obviously. If sound can enter the ceiling, it will travel up to the living areas above I assume there are). As well, sound entering the ceiling cavity can also travel laterally, and simply drop down in the room next to it. We describe this as Flanking Sound. Here's a short article to describe the concept: http://www.soundproofingcompany.com/library/articles/flanking/

You have the wall taken care of. You can assess the ceiling and decide. After that. a solid core door that is sealed will help a lot.

I agree with Matrix. One small point:

You'll want to seal the crack with green glue or elastomeric caulk.

Green Glue isn't a sealant. Only used between panels. Looks like a sealant, but isn't. You'd have quite a goopy mess if left exposed.
