Auricular nerve stimulation techniques for addressing patient disorders, and associated systems and methods. A representative system includes a signal generator having instructions to generate an electrical therapy signal, at least a portion of the electrical therapy signal having a frequency at or above the patient's auditory frequency limit, an amplitude in an amplitude range from about 0.1 mA to about 10 mA, and a pulse width in a pulse width range from 5 microseconds to 30 microseconds. The system further includes at least one earpiece having a contoured outer surface shaped to fit against the skin of the patient's external ear, external ear canal, or both, the at least one earpiece carrying at least two transcutaneous electrodes positioned to be in electrical communication with the auricular innervation of the patient, e.g., the auricular vagal nerve.
