This report summarizes the characteristics of the hearing sensations produced by electrical stimulation using scala tympani electrodes in a postlingually deaf patient (MC1) at the University of Melbourne. An array of 10 electrodes, spaced 1.5 mm apart, was inserted through the round window for a distance of 15 mm around the scala tympani. Biphasic current pulses with each phase fixed at 180 /μsec were used. Fifteen current levels from 67 /μA to 1 rnA could be assigned in 67-/μA steps, and a maximum repetition rate of 1000 rep/sec was possible. More detailed descriptions of the stimulation hardware and the patient's history can be found in previous reports.
