Ok, now that you can speak, lets work this out.
How much space do you have, and do you need to soundproof it. Two general rules to keep in mind are
1) NO PARALELL WALLS. Paralell walls are going to cause some nast slapback/standing wave sounds, so you dont want this. Basically, this is when two sound waves hit each other head on, but with non paralell walls, there are no ways for sound to hit head on
2)BASS TRAPPING. Without proper bass trapping, you are going to have a room that sounds like your in a box. NOt good. Putting up studio foam wont do it either. Look for owens corning 703 or rockwool in your area, you will probably have to look at your local building/insulation suppliers. IN a small room, which is waht you probably have in mind, put this in a 45 degree angle across all corners, preferrably floor to ceiling. This will turn sound energy into heat energy, thus breaking it up.
SOUNDPROOFING
1) ONLY 2 LEAVES. A leaf is any mass in your wall. IN a typical wall, it is both the layers of drywall. The space inbetween the studs is called an airspace. YOU ONLY WANT ONE AIR SPACE, but your leaves need to be as thick as possible. ALso, the larger the airspace, the better. Ask your uncle if he can do double drywall, on both sides.
2) SEALING. Seal all cracks, holes, joints, corners, and boxes. These are prime ways for sound to leak thru, thus putting everything else to waste. You need to use acoustical caulk for this, available at most building suppliers.
3) Isolation- We will talk about this if you have room for two walls.
And there you go. See what a little english can get you
Which planet is the question.
