soundproofing/sealing door between rooms that doesn't need to be opened

[stulaw]

Hi,

I'm renting a room in a house that shares a door with another bedroom (my room has two doors).  My roommate and I want to soundproof the door between our rooms as much as possible, it will never be opened.  We are hoping to spend $100 or less.  We were brainstorming some or all of the following things and are looking for more suggestions:

- Weather stripping the big gaps around the door with rubber self adhesive strips. 

- Sealing the gaps around the door with acoustical caulk (is it any different than regular caulk?)

- Sealing off the gaps around the door with acoustical tape

- Buying the cheapest 4'x8' panel of acoustic foam and putting it over the jam on one side of the door

Any help is greatly appreciated. 

Note: There is a 1.5" gap at the bottom of the door which we didnt know what to do with.  Maybe cut a chunk of wood and seal it in?  The rest of the gaps are about 1/8-1/4"

Here is the link for soundproofing your door.

and you  do want to add the wood at the bottom to reduce the gap so you can use a Transom seal.
