Research on Optimization of Microperforated Acoustic Structures Based on Genetic Algorithm
《Journal of Electronic Research and Application》2025年第2期110-116,共7页Yang Yu Ruilin Mu 
Microperforated panels(MPP)are widely used in noise control applications due to their excellent sound absorption performance.However,traditional single-layer MPPs suffer from a narrow sound absorption bandwidth,making...
