The present invention relates to a structure to reduce noises by aerodynamic force. More specifically, the present invention relates to an aerodynamic noise reducing structure in an area with a high Reynolds number which can reduce aerodynamic noises of an object operated in an area with a high Reynolds number more than or equal to a hundred thousand unit. The aerodynamic noise reducing structure in an area with a high Reynolds number has an uneven part or a plurality of protrusions in an outer surface of an object having a circular, oval, or rectangular cross section.
