Additively Manufactured Deformation‐Recoverable and Broadband Sound‐Absorbing Microlattice Inspired by the Concept of Traditional Perforated Panels

Advanced Materials, Journal Year: 2021, Volume and Issue: 33(44)

Published: Sept. 17, 2021

Abstract Noise pollution is a highly detrimental daily health hazard. Sound absorbers, such as the traditionally used perforated panels, find widespread applications. Nonetheless, modern product designs call for material novelties with enhanced performance and multifunctionality. The advent of additive manufacturing has brought about possibilities functional materials design to be based on structures rather than chemistry. With this in mind, herein, traditional concept panels revisited incorporated development novel microlattice‐based sound absorber additional impact resistance structurally optimized microlattice presents excellent broadband absorption an averaged experimental coefficient 0.77 across broad frequency range from 1000 6300 Hz.
