Title: Research on the Low-frequency wideband sound absorption mechanisms of inhomogeneous microperforated panel metamaterials.
Abstract:
Low-frequency noise has the characteristics of strong penetrability and less attenuation. It has become one of the most significant environmental pollutants and has a serious influence on the natural habitat and social development. However, traditional sound-absorbing materials have poor absorption performance for low-frequency sound owing to weak energy dissipation. In order to accomplish the ideal absorption effect, it is essential to expand the propagation path of the sound waves, which will increase the thickness of the sound waves and is not conducive to engineering applications. In recent years, the development of acoustic metamaterials has greatly broadened the concept of traditional materials and offered a new approach to solve the complication of low-frequency broadband sound absorption. Therefore, this work investigates the sound absorption mechanism, structural design, and engineering application of the inhomogeneous microperforated panel (iMPP) based acoustic metamaterials by the theoretical analysis, finite element simulation (FEM), and experimental examination for the achievement of admirable low-frequency broadband sound absorption.
