DEVELOPMENT OF AN INVESTIGATIVE EXPERIMENT ON DECORATED AIR-PROOF WINDOWS

Acoustic metasurfaces represent a cutting-edge research area in functional acoustic materials. This paper introduces the acoustic metasurface—Decorated Air-proof Window (DAW)—based on practical needs, and designs the research and development of DAW as an investigative experiment. The experiment employs theoretical derivation and finite element simulation software COMSOL Multiphysics for theoretical analysis and design of the DAW and its metal retention device. It encompasses a wide range of experimental components, including COMSOL modeling and analysis, design of the retention device, and measurement of the DAW's transmission performance. Introducing the investigative experiment on DAW into university physics lab teaching enhances the advanced nature, innovation, and challenge level of the experiment. This approach is conducive to nurturing top innovative talents in new materials and lays a solid foundation for improving students' innovative abilities.
