The present application discloses a noise reduction method, device, vehicle and storage medium, and relates to the technical field of noise reduction. When the vehicle receiver is in a working state, the working frequency band of the vehicle receiver is obtained as the target working frequency band, and the information of the vehicle electronic equipment is obtained. The state information is used as the target state information, wherein the state information includes an on state and an off state, and based on a preset mapping relationship, the target operating frequency band and the target noise adjustment factor corresponding to the target state information are determined, wherein the preset mapping relationship includes multiple operating frequency bands And / or the correspondence between multiple status information and multiple noise adjustment factors, the on-board receiver receives noise signals when working, and then performs noise reduction processing on the noise signals received by the on-board receiver through the target noise adjustment factor, so as to reduce the noise. noise to ensure the normal operation of the vehicle receiver.
Description
technical field [0001] The present application relates to the technical field of noise reduction, and more particularly, to a noise reduction method, device, vehicle and storage medium. Background technique [0002] With the development of vehicle electronics, many devices have been added to meet the needs of drivers and passengers for vehicle convenience and comfort. When the vehicle is running, a large amount of noise is generally generated, which leads to the phenomenon that the electromagnetic compatibility (Electromagnetic Compatibility, EMC for short) exceeds the standard seriously. Seriously exceeding the electromagnetic compatibility standard may affect the normal operation of the equipment on the vehicle, and even cause the equipment to fail. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present application proposes a noise reduction method, device, vehicle and storage medium, which can solve the above problems. [0004] In a first aspect,...
