Abstract Considering the growing trend of carbon fiber composites gradually replacing steel as backing material, This paper examines sound absorption capability underwater acoustic metamaterials, focusing on influence different materials (steel and composites). Using COMSOL Multiphysics finite element simulation software, a multi-physical field model with periodic cylindrical cavity is developed. The differences in mechanisms metamaterials are analyzed. results show that although composite-backed cover differs from steel-backed cover, further analysis mode at frequency point corresponding to first second peaks indicates composite material does not alter mechanism metamaterials. Finally, genetic algorithms employed optimize geometry materials, providing theoretical basis for future design optimization backings.

Abstract Multi‐stage porous aerogels have spurred relentless innovation and surpassed traditional boundaries by redefining the landscape of advanced sound management technologies. Harnessing stress‐responsive tuning properties in intricately enhances acoustic attenuation. porosity provides enhanced efficiency across a variety environments. In addition to facilitating attenuation, demonstrating exceptional flame resistance represent an innovative solution specifically engineered for high‐temperature applications. this study, biomimetic multi‐stage aerogel, BMPA, is developed created through mild microbial fermentation, resulting distinctive internal structure. BMPA enabled as high 93%, with ultralight density 0.0518 g cm − 3 . The uncompressed material reduced levels at 1.5 kHz and, when stretched, further improved attenuation 2, 2.5, kHz. Its multistage pore structure lowered noise from 85.7 68.7 dB, achieving total reduction 17 dB—an impressive advancement management! treated inorganic zinc solutions demonstrates significant resistance, V‐0 rating limiting oxygen index value exceeding 60%. groundbreaking development significantly potential next‐generation materials that excel absorption.
