Description
Summary:The word recognition performance of cochlear implant patients using different types of devices & signal processing strategies is compared with benchmarks obtained by testing normal-hearing listeners with continuous interleaved sampler (CIS) & spectral peak (SPEAK) strategies (N = 16 & 9 respectively); signals were processed into 4, 6, 8, & 12 channels for the first group of normal-hearing listeners & by 2-, 4-, & 6-of-20 SPEAK-type processors for the second group. CIS patients used the six-channel Med-El CIS-Link processor & two eight-channel devices, the Advanced Bionics Clarion 1.2 & the Mel-El Combi-40 processors (N = 25, 60, & 60 respectively); SPEAK strategies were used with Nucleus 22 & CI24M devices (N = 59 & 66 respectively). Results indicate that many patients using eight-channel devices matched the mean performance of normal-hearing listeners with eight channels; average patient scores, however, matched the mean performance of normal-hearing listeners on four-channel processors. 1 Figure, 3 References.
