Actively Reconfigurable Segmented Spatial Sound Modulators (Adv. Mater. Technol. 4/2024)

Spatial Sound Modulators In article number 2301459, James Hardwick and co‐workers introduce spatial sound modulators (SSMs), novel devices that combine traditional acoustic metasurface pixel units into custom‐shaped segmented elements. An SSM fabrication method is detailed using off‐the‐shelf 3D printers and bespoke control electronics, completing an end‐to‐end methodology from conception to realization. Further enhancements to the technique are explored through hybrid SSM devices with both static and dynamic elements.
