Electrical Stimulation of the Human Cochlea — Psychophysical and Speech Studies

  • Y. C. Tong
  • G. M. Clark


This report describes psychophysical and speech studies conducted on two of our post-lingually deaf patients implanted with multiple-electrode cochlear prostheses. The objectives were to study the nature of the hearing sensations produced by the individual electrodes, and to investigate the feasibility of the transmission of speech information to the higher centres by means of cadences of stimulation using one electrode at a time. Two totally deaf patients (MC1 and MC2) participated in these studies.
