1. A gypsum panel having sound-absorbing properties, the gypsum panel comprising: a perforated gypsum body having a plurality of holes; anda sound-absorbing cover layer attached to one side of the gypsum body and having through-holes of a smaller size than the holes, the through-holes having an average diameter of 10 μm to 40 μm,wherein at least one of the holes of the perforated gypsum body is overlapped with at least one of the through-holes of the sound-absorbing cover layer, and the overlapped holes are extended through an entire thickness of the gypsum panel. 2. The gypsum panel according to claim 1, wherein the sound-absorbing cover layer is a non-woven fabric formed of at least one of glass fiber, polyester fiber, and pulp. 3. The gypsum panel according to claim 1, wherein the gypsum body includes a gypsum board and a finishing material attached to one or both sides of the gypsum board. 4. The gypsum panel according to claim 1, wherein the gypsum body is a finished tile. 5. The gypsum panel according to claim 1, wherein the holes have an average diameter of 0.5 mm to 20 mm. 6. The gypsum panel according to claim 1, wherein the sound-absorbing cover layer comprises a finishing layer having a pattern printed on an outer surface thereof. 7. The gypsum panel according to claim 1, wherein the gypsum panel has an air permeability of 100 L/m2/s to 2,000 L/m2/s at 200 Pa. 8. The gypsum panel according to claim 1, wherein one side of the sound-absorbing cover layer is attached to the one side of the gypsum body, and the other side of the sound-absorbing cover layer is disposed to face a ceiling or a wall of a building. 9. A method of manufacturing a gypsum panel having sound-absorbing properties, the method comprising: preparing a perforated gypsum body having a plurality of holes; andattaching a sound-absorbing cover layer to one side of the gypsum body, the sound-absorbing cover having through-holes of a smaller size than the holes,wherein the through-holes have an average diameter of 10 μm to 40 μm and the holes have an average diameter of 0.5 mm to 20 mm, andwherein at least one of the holes of the perforated gypsum body is overlapped with at least one of the through-holes of the sound-absorbing cover layer, and the overlapped holes are extended through an entire thickness of the gypsum panel. 10. The method according to claim 9, wherein the sound-absorbing cover layer is a non-woven fabric formed of at least one of glass fiber, polyester fiber, and pulp. 11. The method according to claim 9, further comprising: printing a pattern on an outer surface of the sound-absorbing layer to form a finishing layer after said attaching the sound-absorbing layer to the one side of the gypsum body. 12. The method according to claim 9, further comprising: directly printing a pattern on the sound-absorbing cover layer by partially coating a non-woven fabric with a polyvinyl chloride (PVC) sol. 13. The gypsum panel according to claim 1, wherein the sound-absorbing cover layer comprises: a non-woven fabric; anda pattern of polyvinyl chloride (PVC) directly and partially coated on the non-woven fabric.
