I'm no expert so I can't really answer your question, but there's a useful chart of densities and NRC ratings vs. frequency for Roxul batts and boards and Owens - Corning 703/705 at the site linked below. I think I read a comment by Mr. Winer somewhere that rock wool and fiberglass perform essentially the same. I used Roxul boards and batts rather than the comparable OC stuff since the rock wool is about half the price of fiberglass.
