The invention relates to the technical field of acoustic metamaterials, and provides an acoustic metamaterial cabin wall surface acoustic wave regulation and control interactive progressive design method which covers a cabin wall and is characterized in that the two sides, making contact with different media, of the cabin wall surface serve as a surface A and a surface B respectively; the method comprises the following steps: S1, selecting a periodic structure unit based on an acoustic metamaterial to establish a basic three-dimensional structure; s2, collecting characteristic parameters of the basic three-dimensional structure and corresponding output sound pressure levels as a data set; and S3, expanding the data set through a data semantic augmentation method based on a genetic algorithm. According to the acoustic metamaterial cabin wall surface acoustic wave regulation and control interactive progressive design method, manufacturability of a design structure is fully considered, a three-dimensional model is fed back based on a manufacturing process constraint, a manufacturing limit size and application environment limitation are considered, and structure-manufacturing-performance collaborative optimization is realized.
