Dynamic Schwarz Meta‐Foams: Customizable Solutions for Environmental Noise Reduction
Abstract: In an era marked by increasing environmental challenges affecting human well‐being, traditional acoustic materials struggle to effectively handle the diverse and multi‐frequency nature of harmful environmental noises. This has spurred a demand for innovative acoustic metamaterial solutions by utilizing sustainable design strategies. This research introduces tunable Schwarz metamaterial capable of transforming into a soft meta‐foam to solve the complex problems of varying environmental noises. This study primarily focuses on adjusting single to multiple sound‐blocking bandgaps mechanism using a multi‐layered approach, incorporating the Schwarz P‐type triply periodic minimal surface (TPMS) and its elective soft foam counterpart, known as tunable Schwarz meta‐foams (TSMF‐x). The tunable design parameters of the unit cell, multi‐layered TPMS, and soft programmable TSMF‐lichen version are comprehensively explored including a fire‐safety test. The results demonstrate these enhanced flame retardant meta‐foam families have the potential to be used for mid‐to‐high‐frequency environmental noises in industrial equipment and smart homes for sustainable architecture and environmental health applications.
