Cover Story: The variable noise spectrum for many practical application scenarios requires adjustable sound absorbers, especially in low-frequency ranges. In this study, the adjustable acoustic metamaterial of multiple parallel-connection Helmholtz resonators with tunable apertures is prepared through the low-force stereolithography of photopolymer resin, and its absorption performance can be altered directly without the refabrication of new sound absorbers. The achievement of excellent sound absorption performance for various target frequency ranges is favorable for promoting the prevention and control of noise pollution. View this paper
