We show how muscle-driven sound production mechanisms (e.g., those found in fish and arthropods), are limited by muscle contraction speeds, which restrict signal frequency and radiation efficiency.

Airflow-driven mechanisms, particularly those using myoelastic aerodynamic (MEAD) principles, overcome these constraints to enable efficient, high-frequency sound production.

MEAD has evolved convergently across several different clades of tetrapods, including basal mammals, toothed whales, and birds, supporting complex and long-range acoustic communication.
