Demographic information for Experienced Cochlear Implant (ECI) subjects tested at a single visit after at least 24 months of CI experience. Subject characteristics described include age in years, gender, implant ear, duration of CI use, internal CI device and pulse rate, etiology of hearing loss (HL), duration of high-frequency (HF) severe-profound (S/P) hearing loss, average low-frequency threshold shift (averaged over 250, 500, and 1000 Hz), and contralateral hearing aid (HA) model used (“none” indicates subject did not wear a HA). The specific electrodes tested and the electrodes that could not be pitch matched (out of range) are also given in the last two columns.
