My question is in regards to laminate wood flooring underlayment. The
photos at the following link explain it best.

In the photo you are looking at the center of the room that has a 4x4
support post. This where 3 different types of floor merge together.
A parquet wood floor in the dining area, a vinyl floor in the kitchen,
and butcher paper(stop gap) over 3/4" plywood, where a carpet use to
the exist. The plan is to replace the parquet and vinyl with the same
laminate flooring. The question is in regards to underlayment. Under
the parquet is 3/8" particle board and under the vinyl is 1/2"
particle board. The particle board is nailed down, not screwed into
the 3/4" subfloor. Should we do:
a) leave the 3/8" particle board and put down new 3/8" particle board
to match the height
b) Remove all the existing particle board and replace with either
1) the best foam underlayment that the laminate floor
2) no underlayment, just a moisture barrier on top of the 3/4"
3) cork (4mm) underlayment
4) Quickstep 1/4" softboard (.30/sq ft.)
c) Use new and inexpense 3/8" or 1/2" particle board screwed down.
My biggest concerns are sound and trying to achieve the solid like
feel of real wood with this laminate floor.
The laminate floor is the Harmonics from Costco which I hear is the
Quick-Step white box stuff. 8mm thick.
