ABSTRACT A vibration absorbing panel having an elastic core sandwiched between a pair of facings of solid wood, plywood, various boards, metal, etc. The elastic core is in the form of at least one sheet of natural or synthetic rubber or the like which is corrugated to provide alternating flat ridges and sloping webs. Lying in two parallel planes, the flat ridges have their outer surfaces bonded to the rigid facings. The corrugated sheet of rubber or the like has fibers implanted, electro- statically or otherwise, on all its surfaces except the glued outer surfaces of the ridges. Also disclosed is a floor construction comprising a plurality of composite panels each configured as above. The panels are joined together by tongues and grooves and have their lower facings secured to an understructure in a manner suiting each specific application.
