An engineered hardwood flooring system includes tongue and groove core planks, each having a hardwood top plate glued to the top surface of the core plank. The hardwood top plate is made by gluing thin strips of hardwood to form a planar top plate which is attached to the core plank. The hardwood top plate is coated with a polyurethane finish or the like to protect the luster and beauty of the hardwood. The core plank includes a plurality of holes extending completely through the core plank from a top surface of the core plank to a bottom surface of the core plank. The holes are spaced apart and arranged in a pattern consisting of alternating staggered rows of holes. The purpose of the holes in the core plank is to attenuate acoustic energy propagating within the core plank, and thereby reduce the level of noise caused when people walk on the floor.
