Cochlear implant (CI) subject demographics

Subject ID	Age (years)	Durationa of hearing loss (years)	Duration of CI use (years)	Etiology	Implant type	Default channel stimulation rate (pps)
C1	71	25	6	Unknown	HiRes90K	5156b
C2	81	35	5	Unknown	HiRes90K	1657c
C3	34	0	6	Atypical Meniere’s	HiRes90K	5156d
C4	49	0	30	Genetic	HiRes90K	5156
C5 (L)	48	7	8	Hereditary	HiRes90K	5156d
C5 (R)	48	7	17	Hereditary	HiRes90K	5156d

^aDuration of severe to profound hearing loss is based on subjects’ self-report of the number of years they were unable to understand people on the telephone prior to implantation

^bFor the dropped map with the dead region size of 14 electrodes, a channel stimulation rate of 2900 pulses per second (pps) was used

^cFor the dropped map with the dead region size of 14 electrodes, a channel stimulation rate of 4972 pps was used. For the map with full 16 channels (i.e., no-dead region), a channel stimulation rate of 4094 pps was used

^dFor the dropped map with the dead region size of 14 electrodes, a channel stimulation rate of 2900 pps was used
