simple floor question

[firefox]

I have just ripped off some rotted particle board and linoleum  tile from the original floor, which is in reasonavle shape except for a few sections.
My plan was to put some 3/4"  plytwood down on top of it which I happened to have scrounged a while back. Then put some kind of floor covering on that.

For some reason my brain says to put down 30# felt before putting down the plywood, but now I am not so sure that is a good idea,

Any suggestions? I want to do a reasonable job on this but I am not going
overboard at this time since I will probably be moving in a year or two.
But I am not interested in doing shoddy work either.

Considering the deafining response to my question, I will assume that it
is not necessary or disireable to put the felt down between the two layers of floring.

I thought it was a simple question

Oh shoot! I forgot that part of the question.    NO don't do it. It could lead to squeaks believe it or not.

It was recommended between pine floor boards and sub floor but nailed every 5 inches x about 18" - doesn't sound good for sheet products though.

Sorry  I didn't reply sooner - working out from the shop and little forum time lately.

  I kinda thought as much, but I just wasn't sure.
