The invention claimed is: 1. A floor system comprising: a first impact-absorbing material disposed directly on a floor slab; and a second impact-absorbing material disposed on the first impact-absorbing material and having a higher density than that of the first impact-absorbing material, wherein the second impact-absorbing material is a wood board or an inorganic board having a higher density than that of the first impact-absorbing material by 0.5˜1.95 g/cm3, wherein the first impact-absorbing material has a density in a range of 0.05˜0.5 g/cm3, and wherein the second impact-absorbing material has a density in a range of 0.8˜2.0 g/cm3. 2. The floor system according to claim 1, wherein the first impact-absorbing material is made of foamed plastic or rubber. 3. The floor system according to claim 1, wherein the second impact-absorbing material is divided into a plurality of impact-absorbing material members arranged parallel to one another in longitudinal and transverse directions, and the neighboring members of the second impact-absorbing material are connected to one another by using clamps. 4. The floor system according to claim 1, wherein the first impact-absorbing material has protrusions extending toward the floor slab. 5. The floor system according to claim 4, wherein the protrusions are formed by vertically protruding certain portions of the first impact-absorbing material downward toward the floor slab, or are formed separately from the first impact-absorbing material. 6. The floor system according to claim 1, wherein the system has a lamination structure of the first impact-absorbing material, the second impact-absorbing material, a heat insulating material, a radiator and a finishing material, which are laminated in this order from the floor slab. 7. The floor system according to claim 6, wherein the radiator has a pipe shape. 8. The floor system according to claim 6, wherein the radiator includes plate-shaped panels each having inner flow paths. 9. The floor system according to claim 1, wherein the first impact-absorbing material has a thickness in a range of 20˜30 mm, and the second impact-absorbing material has a thickness of 10 mm±5.
