Evaluation of Electrostimulation of Hearing by Evoked Potentials

  • Roger C. Simon

Electrostimulation of hearing has been classified into two types: electrophonic (Stevens 1939) and radiophonic (Hoshiko 1969). The former method involves direct electrical stimulation of a subject and may be afforded by placing one of two leads from an audio oscillator in the ear canal filled with salt solution and attaching the other electrode to the wrist. Often, a DC polarizing voltage is used as an adjunctive measure which improves clarity of perception. The second method involves amplitude modulated radio frequency waves whereby subjects have reported “hearing” tones in a 250 Hz to 20,000 Hz range. Radio frequencies often vary between 40 kHz and 100 kHz though other frequencies have been used.
