Cicadas generate sound through the interplay of tymbal buckling and body resonance, but a unified framework explaining the diversity of calls across species has been absent. In this study, the authors conceptualize the cicada’s sound-generation mechanism as a naturally occurring metastructure, characterized by periodically arranged ribs and inherent frequency filtering.
