Okay,
I live with other people in a big house and I am in the basement. I get to enjoy listening to "squeaky" floorboards all night and all day. My life is wonderful. :) So I want to build like a room-within-a-room, my fortress of solitude where no sounds get in or out. Actually that's being extreme as long as I reduce the STC substantially I will be happy. I've been researching the best ways to soundproof rooms. One big topic that seems highly important is decoupling walls and ceilings. Makes sense to me. So I figured I would go to the extreme and not use existing ceiling(floor joists) as studs for basement ceiling. I've also read about how having lots of space in between drywall is a good thing. So my idea, was to use 2x10's for the wall and ceiling studs of my "fortress of solitude". I would basically create lots of double-sided wall panels filled with rocksol insulation. Using 1/2" on one-side of the 2x10 studs and 5/8" on the other side. Using 2x10 studs for the walls should give them more stability.

And lastly, I don't care that this is a permanent solution. So I like my idea for portability reasons. Is this idea okay? The 2x10 studs create more space between each sheet of drywall(which I read is a good thing). The height from the concrete floor to the floor joists above me is a standard 8 feet I believe. So using 2x10's on the ceiling doesn't give me as much head space as I like but it should still be just enough for me to stand under. Thanks for all comments.

The 2X10s would be overkill. I would focus your money on db-3 acoustical barrier and celotex fiberboard. These together will push the STC over 100. Building the detached walls will help the STC significantly so you may only need one or the other. If you decide to only use one, I would also use 5/8" Sheetrock.

After your done if you want to improve the sound quality within the room I would recommend my acoustic panels: https://www.Etsy.com/shop/evolutionacoustics

I am not sure you have enough field experience with the statements you have made on this thread...
In my decade of field work ( assembly design and field testing have I never seen 100 STC ....maybe only reading 4k and up but never based on the way STC testing is done...
I would like for you to post proof of an assembly ASTM E90-09 or ASTM E90-02 test results for the material you recommended. Even our Mass loaded vinyl can not reach those values standing alone.

To the thread writer
Squeaky floor boards need to either be re screwed from above or subfloor blocking to pull the subfloor back down.
As for increased STC you will need to increase the mass to at least 8-10 lbs per sqft. minimum  based on standard 5/8" sheet rock that would be about 4 layers ...
This falls under " Mass Law"  where you must double the weight or density in order to achieve 5 db loss over what is heard through a standard interior wall. 
If you want to build the "Tomb" then you are looking for upwards of 15-20 lbs per sqft.
