Just came back to check this thread because I never got any notification that there were replies even though I always have instant email notification checked.
Anyways, there is no paper under the flooring. It was nailed directly to the subfloor with 1" nails through the tongue, so about 3/4" of the nail is in the subfloor.
It's 3/4" subfloor with I-joists on 16" spacing. The was no noise from the floor before installing the hardwood.
It's definitely the joints between the boards that are making the noise, they are very tight. Can't even get powder graphite to get in between them.
