[header] How to soundproof a wall or ceiling [title] Install the basic frame and one side of the wall, leaving the wood studs exposed. [step] You'll need the frame of the wall already installed, as well as one side of the actual wall. You will then stuff the wall with sound-proofing before sealing up the wall. 
[substeps] If you're working on a wall, you can seal up either side first--it shouldn't matter. If you're working on the ceiling, you want to soundproof it from the top.
