The utility model relates to a device for reducing wind noise of a seaside microphone, which comprises a turbulence shielding cylinder and a rain cover, a plurality of spiral linear metal wires are wound on the outer surface of the turbulence shielding cylinder at equal intervals, and a plurality of spiral linear metal wires are wound on the outer surface of the rain cover at equal intervals. According to the utility model, the spirally wound fine lines are arranged on the outer surface of the microphone measuring device to reduce eddy sound and turbulence sound generated by sea wind blowing through the microphone part; through the physical structure wind noise resistance technology, the wind noise is controlled from the generation source and the propagation path of the wind noise of the microphone; the wind noise intensity of the microphone can be effectively reduced, the detection performance of sound detection equipment can be improved, and finally, the self-noise of the microphonedue to the fact that sea wind blows over the microphone in a seaside or island reef environment can be effectively reduced.
