The invention provides a wheel noise reduction device and a noise reduction method, and belongs to the technical field of wheel noise reduction. The wheel noise reduction device comprises a noise reduction ring, a plurality of groups of elastic assemblies and a plurality of groups of noise reduction assemblies; the noise reduction ring is used for being installed on a wheel rim. A plurality of noise reduction spaces are arranged in the noise reduction ring at intervals in the circumferential direction of the noise reduction ring, and the noise reduction spaces are connected with the outer circumferential wall of the noise reduction ring; the multiple elastic assemblies are arranged in the noise reduction ring in the circumferential direction of the noise reduction ring at intervals. The multiple groups of noise reduction assemblies are in one-to-one correspondence with the multiple noise reduction spaces, and the noise reduction assemblies are arranged in the corresponding noise reduction spaces and connected with the concave inner walls of the noise reduction spaces; the noise reduction assembly is further provided with a plurality of noise reduction holes. The noise reduction method adopts the noise reduction device. According to the wheel noise reduction device and the noise reduction method, the noise reduction effect of the wheel can be greatly improved, and noise pollution generated by the wheel is reduced.
