2.3 Cochlear implant device programming
Approximately two-three weeks after the implantation, the initialactivation was done by a pediatric audiologist. The audiologists verify the children’s hearing thresholds with the CI at each programming session using audiometric sound field-testing. Sound detection thresholds are measured at 0.25, 0.5, 1, 2, and 4 kHz using warble-tone or narrow-band stimuli, with speech presented by a monitored live voice. The children’s thresholds currently range from 30 to 40 dB HL, with speech awareness thresholds at about 25-35 dB HL.
