Mean | Median | SD | Mean | Median | SD | |
Unaided PTA threshold at the time of testing (HA) or pre-implant unaided PTA threshold (CI) (dB) | 64 | 67 | 13 | 101 | 100 | 15 |
Aided PTA threshold at the time of testing | 26 | 25 | 6 | 20 | 20 | 5 |
Age at first CI (months) | 25 | 14 | 29 | |||
Age at second CI (months); N = 33 | 54 | 44 | 38 |
Note: PTA = pure tone average. PTA thresholds are given in dB hearing level for the three speech frequencies of 500, 1000, and 2000 Hz, for the better ear.
