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?

I suggest you check the 'Acoustiguard' website. I envy your opportunity to create a glorious sound room of about the size I would appreciate.

All the walls will be double layers 5/8" sheetrock with green glue between the sheets.

Ceiling is 11' high and will be subdivided into six partitions; the partitions or soffit that forms them will hold the HVAC and lighting.

If I was use I would consider using quiet rock for all your drywall applications. Best of Luck

Stickman, re your floors, you have been very spoilt by having concrete floors in your current room.

Any suspended floor you have now will need the speaker isolated (de-coupled) from it, not spiked or coupled in any way, otherwise the floor will become a sound board for the speakers.

There is one way for you to be able to spike (couple) your speakers in this room to get the very best out of them still. It radical , but then maybe you are as much as I am. Seeing you have a basement underneath this suspended floor, you can have two concrete post poured from the basement floor up to where your speakers are positioned, this way they'll still be on a concrete support.
