Can you soundproof a room to keep noise out?

If outside noise is your main problem, you can soundproof your house or apartment several ways. Caulk cracks in your window frames, install heavy, sound-damping curtains or use window inserts to reduce 50 to 70%* of the noise as well as block drafts to lower energy bills. Insulating your walls and ceiling also helps.
