In article number 1903699, Nicholas X. Fang, Xuanhe Zhao, and co‐workers propose a meta‐gel to achieve tunable acoustic properties over air‐water‐solid ranges and broadband frequencies. The meta‐gel consists of patterned channels in a tough hydrogel matrix, where air, water, or liquid metal can be purged through the channels. The meta‐gel's acoustic impedance can be tuned by varying the geometry and volume ratio of the channels and properties of the filler media.
