New home cinema - Room within a room questions

Hi all.

I am at the very early build stage of a gaming room / home cinema room in the back garden. I don't want to annoy the neighbors so I have put in a concrete slab with the intention of building a room in a room set up.

My question is where online can I find a simple guide on how wall thickness and spacing? I'm looking at 2x4 and 2x3 walls or 2x4 and 2x4 and would like to get the spacing and mass right to get the lowest frequencies I can reduced losing the least internal space.

I understand the basic theories but there must be some pre worked out examples or simple rule of thumb examples to save any in depth calculations etc...

The first part of the room (it will have a second workshop area attached at a later date) has a slab area of 3.9m X 4.8m (approx, it is not square and was made to fit the garden space as best as possible)

Cheers for any help!
