TABLE I.

Demographic information for participating subjects. In the middle columns, time is listed as years, months (with averages in the bottom row). Time post CI was calculated from the date of psychophysical testing. SNHL = sensorineural hearing loss. + p = positioner. PTA = pure-tone average at 250, 500, and 1000 Hz. The pre-CI PTA was not available for subject C39, who transferred to our center after implantation.
