audiitide
Audiitide is a term used in speculative contexts to denote a hypothetical material or composite with advanced control over acoustic waves. It is not an established material, and there is no peer-reviewed evidence of its existence as of now.
Etymology—The name combines audio, from Latin audire “to hear,” with the suffix -tide, a convention in some
Theoretical properties—In theoretical discussions, audiitide is imagined as possessing tunable acoustic impedance, high anisotropy, and frequency-selective
Context and usage—The concept appears in science fiction, thought experiments, and speculative design exercises about future
Relationship to related fields—Audiitide is connected to areas such as acoustic metamaterials, phononic crystals, and sonic
