A soundproof woody flooring, comprising:
- a plurality of pieces each comprising a top woody board, a sound insulating sheet glued to said board and a perforated woody board glued to said sheet on the opposite side thereof from said top woody board;
- said plurality of pieces having generally opposed tongue and groove formations thereon so that each piece of said plurality is engageable with the groove and tongue formations, respectively, on an adjacent piece of said plurality of pieces, each said piece of said plurality of pieces being further formed with a first notched surface below said tongue formation thereon and a second notched surface below said groove formation thereon, the corresponding said first and second notched surfaces of any pair of adjacent pieces forming a groove-like cavity upon engagement of the corresponding tongue and groove formations thereof;
- said plurality of pieces being arranged and joined to one another along the longitudinal edges thereof with transverse edges being located in generally staggered relation from each other to the longitudinal direction to avoid alignment of the transverse edges so as to form an assembly of pieces;
