Sound proofing, what is enough?

Hi,

I am working out some plans on my yet to be build HT room.
The Front and Right side walls are both double brick walls with an air gap in between and small air vents in the outer wall. Both walls have a window in them and all is facing the outside. The Left wall is a solid double brick wall with no air gap in between, and is connected to the internal part of the house. The back wall is going to be newly build, and I have currently planned for a double stud plasterboard wall with double (airlock) entry doors. The flat ceiling has 5 exposed roof joist unevenly spaced over the width of the room measuring 200mm in height and 70mm in width. On top of these joist is placed the ceiling, consisting out of 18mm thick timber lining boards, followed by probably 100mm of insulation and a sheet metal roof.

I am considering using channels clad with 2 layers of plasterboard sandwiched together by green glue on the walls, if I don't lose to much width doing so. What kind of effect/improvement can one expect using such a solution?

What to do with the ceiling is wide open for discussion. I prefer not to close of the whole ceiling at the bottom of the joist, making the height of the ceiling less than 2.3 meter, but what other options do I have that are sufficiently compared with the rest of the room.

For the windows, I am considering going for triple glazed units.

I do live in a quiet area, so my biggest concern is not to keep outside noises out, but more to keep inside noise in. Although, when it is raining, the noise levels in the house/room dramatically rise.

Your link doesn't work, or I don't have access. It is redirecting me to the main page.
