Sound insulation and ventilation superstructure based on mixing principle
The invention discloses a sound insulation and ventilation superstructure based on a mixing principle. The sound insulation and ventilation superstructure comprises a Helmholtz resonator array and a curled space structure, the Helmholtz resonator provides a high-performance narrow-band sound insulation acoustic characteristic, and the curled space structure provides a wide-band sound insulation acoustic characteristic. By utilizing the coupled Helmholtz resonator array, the sound insulation capability of the broadband with the curled space structure is remarkably improved, and high-performance low-frequency broadband sound insulation can be realized. The Helmholtz resonator array and the curled space structure are arranged in a space mixing mode, under the condition that new thickness is not increased, high-performance low-frequency broadband sound isolation is achieved, the thickness of the structure is reduced, and the requirement for lightness and thinness of a sound insulation material is met. The composite acoustic metamaterial gets rid of the limitation of a traditional composite acoustic metamaterial, does not increase new thickness while keeping high-performance broadband low-frequency sound insulation and air circulation, shows strong application potential, and can be applied to the fields of aerospace, ship engineering, traffic engineering, constructional engineering and the like.
一种基于混合原理的隔音通风超结构，包括Helmholtz谐振器阵列和卷曲空间结构。Helmholtz谐振器提供了高性能窄带隔声的声学特性，卷曲空间结构提供了宽带隔声的声学特性。利用耦合Helmholtz谐振器阵列，卷曲空间结构宽带的隔声能力显著提高，可实现高性能的低频宽带声隔离。本发明通过空间混合布置Helmholtz谐振器阵列和卷曲空间结构，在不增加新的厚度的条件下，实现了所述的高性能低频宽带声隔离，并且节约了结构的厚度，与隔声材料轻薄的要求相一致。本发明摆脱了传统复合声学超材料的局限，在保持高性能宽带低频隔音以及空气流通的同时，没有增加新的厚度，显示出强大的应用潜力，可应用于航空航天、船舶工程、交通运输工程以及建筑工程等领域。
