Gary, I have seen you quote from this area of NOFMA many times. You may have overlooked this publication.

Here is the link that talks about inspecting a floor from the standing position, I think the info is down about three pages.

Hey Buddy, Thanks. It's funny, all the reports and publications I've read and I forgot those. From a Stone's tune, " What a drag it is getting old."

NOFMA sets standards for manufacture/milling and grading/installation.
Writes Technical Information and bulletins.

They don't have standards of manufacture/milling/grading on the site, that I can find. You can write them for the book.

we had just gone through the same thing with one of our installers. fist brown paper, why paper ,and not something that would help in many other areas, ,moisture and for sound , wood agianst wood makes the sound you are talking about ,it may be that simple ,an installer for us used something other then what we allways use and the very same thing , alond with how it was installed, not enough nails , we replaced a floor with the same promblem and used the correct "paper" and correct nail depth and spacing ,presto the promblem was gone , moisture to me is not whats wrong here , installer cut some corners
