I would say that old shingles are much thicker than a single layer of asphalt felt, and that even the felt comes in different thicknesses. I have heard that mass more than anything else, absorbs sound, so if shingles had to be removed, I would go for several layers of the thickest felt I could get, unless someone tells me they tried that and it didn't work.
