Treating Floor in New Construction - Reducing Footfall and Vibration

Looking for some good ideas/solutions to treating my new dedicated music room's floor.  The room will be fairly large at 22w x 29L, built on the main floor of the new house with a basement below.  My current room is in my basement with concrete floors so footfall is never an issue.

I have asked the engineering firm to give me some recommendations on making the floor stronger structure wise; not sure what they will suggest, maybe floor joist on more narrow centers, say 12 inch vs 16.  

Have you tackled this issue?  What about mass loaded vinyl (MLV); would a layer of heavy vinyl between the OSB floor boards and carpet pad help?  Use two layers of OSB flooring and glue them together?  Ideas?

My room is over the garage. Fortunately the garage is quite high so I was able to strengthen the music room floor by running two 10in deep joists under and perpendicular to the existing joists. 
I laid a very dense sound deadening material

 plus a thin insulating layer over the existing chipboard floor with an  engineered wood floor on top. Works really well no movement in the floor and no bass emphasis from the floor even with 2 big subs.
