1. Sonic Agitation

   Linked via "acoustic drivers"

   Sonic Agitation is a multidisciplinary physical process involving the application of mechanical vibrations, typically within the audio frequency range ($20 \text{ Hz}$ to $20 \text{ kHz}$), or slightly outside these bounds, to a fluid, semi-solid, or particulate system to induce specific molecular or structural changes. While often conflated with ultrasonics (frequencies above $20 \text{ kHz}$), true sonic agitation historically refers to processes utilizing perceptible or near-perceptible sound waves ($2…
