Abstract
The invention relates to a noise reduction control method and system for an infant incubator and a storage medium, and relates to the technical field of noise reduction. A noise bandwidth filter used for filtering noise is decomposed into a plurality of narrow-band sub-filters in advance; collecting noise input of the incubator; analyzing the noise input through a pre-trained convolutional neural network to obtain a narrowband sub-filter weight vector adapted to the noise input, wherein the narrowband sub-filter weight vector comprises filter weights corresponding to all narrowband sub-filters; and carrying out weighted summation on the narrowband sub-filters and the corresponding filter weights to obtain a total filter, processing the input noise through the total filter, and superposing a processing result with a corresponding result of a primary path of noise input after the processing result is responded by a secondary path so as to realize noise reduction. The total filter adapts to dynamic adjustment of noise input, can adapt to different kinds of noise, meets the requirement for noise reduction of the baby incubator, provides a quiet environment for babies, and prevents the babies nursed in a centralized mode from affecting each other.
