Solid Hardwood, Engineered and Laminate Flooring - Sub-Floor for 3/4 Oak??

our sub-floor is 3/4 OSB t & g.. We are going to have Oak strip installed. I've heard / read that you don't really want to put hardwood strip over OSB. I was wondering about something to put between the two... I've even entertained the idea of a thin layer of CORK between them, for quiet, comfort, and some protection from anything that might pop up.

Any Thoughts on this??? The flooring is going in a new bedroom and the dining room

The issue with using OSB is it tends not to hold nails as well as the recommended 5/8" or 3/4" exterior grade plywood. Many do however consider 3/4" OSB a comparable substrate.

The National Oak Flooring Assoc. reports that sound control measures with nail down wood tend to be jeopardized by the nails. Thus, sound control underlayment should not be penetrated by nails. Sound travels the nail the surface below and negates the sound control. Where floors touch walls or fixtures, these can transmit sound to other parts of the house. Sound control is usually an issue where the floor is being installed over other living spaces such as in condos, apartments, and townhouses or second stories in residences.

Sound control matting or foam are typically used beneath floating floor systems. Acoustical cork is applied to subfloors with recommended adhesive.

I know about the OSB, I didn't want it to begin with I wanted Plywood, but the lumber yard pushed, and my honey accepted it. I can only hope that the OSB works over the long haul.
