Here's the best you can do (why am I telling people this? geeze, it takes money out of my pocket. Hey buddy, you got a buck for a cup of coffee?)
Where the conduit enters the room (through the drywall), maker certain the conduit does not touch the drywall. You can use a flexible caulk (Ted has some acoustic caulk that will work well) to seal the gap between the conduit and drywall.
Where the conduit passes through framing, cut the hole bigger than the conduit and do exactly the same thing ... don't let it touch the framing...use caulk to seal the gap.
Where the conduit runs through a wall, make certain it cannot contact either side of the walls (back side of the drywall) or any framing ... you don't want rattles. Where you use clamps or attaching brackets to secure the conduit inside the walls, get slightly oversized and use pipe wrap between the bracket and the conduit.
If you want to go "over the top", wrap the entire conduit run.
At each end, once your wires are pulled, plug the ends with fiberglass but make sure you can pull that fiberglass out in case you run a new wire in the future.
