摘要
微穿孔板由于结构简单、环境友好以及良好的吸声性能,一经马大猷先生提出就引起了极大的关注。文章介绍了微穿孔板声阻抗计算理论的发展,综述了从单微穿孔板共振系统到耦合多微穿孔单元共振系统吸声性能研究的最新进展。微穿孔板与其他类型的吸声结构复合可带来额外的声吸收峰,进一步拓展吸声带宽;微穿孔板与有源控制技术相结合可产生良好的可调谐特性,有效提升低频吸声性能。此外,回顾了基于穿孔板衍生的管束穿孔板吸声结构的最新研究进展,复合多功能的结构设计在低频宽带降噪领域具有巨大的应用潜力。最后,展望了微孔穿板和管束穿孔板结构的未来发展方向。
The microperforated panel structure proposed by Maa Dah-You has attracted significant attention for its good sound absorption performance,environmental friendliness and simplicity of structure.This article briefly introduces the development of impedance prediction models for the microperforated panel and reviews the advances in absorption performance from the single microperforated panel resonator to the coupled multiple resonance systems.The combination of microperforated panels with other types of sound absorbing structures can introduce additional absorption peaks,thus further expanding the absorption bandwidth.Integration with active control technologies achieves good tunable characteristics and effectively improves the low-frequency sound absorption performance.This article also reviews the recent research progress on the perforated panel with tube bundles and the composite multifunctional structure designs,which hold significant application potential in the field of low-frequency and broadband noise reduction.Finally,the article discusses the future development of microperforated panels and the perforated panel with tube bundles.
