Abstract

Abstract: Suppression of low-frequency noise has always been a key focus and challenge in the field of noise control. Due to the limited effectiveness of traditional sound-absorbing materials in absorbing low-frequency noise, metastructure have emerged as a hot research topic. Among them, biomimetic structures, as an important branch, show great potential in the field of low-frequency noise absorption. In this study, a acoustic absorption metamaterial inspired by a conch is designed, where two spiral sound channels are coupled in a single unit cell, proposing a Conch-like bidirectional acoustic absorption metamaterial (CBAAM). CBAAM sampleswere produced by additive manufacturing (AM) technology, and their bidirectional acoustic absorption performance is validated through finite element simulations and acoustic impedance tube tests, showing a absorption performance of (168 Hz, 438 Hz) at face 1 and (166 Hz, 462 Hz) at face 2. The study revealed that the acoustic absorption performance mainly contributed from resonant effect, and some key geometric parameters had significant impact on the acoustic performance of CBAAM. Additionally, the study explored the composite of CBAAM with other different materials to analyze the influence of various material compositions on its compressive mechanical properties. The lightweight and bidirectional sound absorption performance of CBAAM may have broad application prospects in the field of acoustic control.
