A channel-selection criterion for suppressing reverberation in cochlear implants.
Little is known about the extent to which reverberation affects speech intelligibility by cochlear implant (CI) listeners. Experiment 1 assessed CI users' performance using Institute of Electrical and Electronics Engineers (IEEE) sentences corrupted with varying degrees of reverberation. Reverberation times of 0.30, 0.60, 0.80, and 1.0 s were used. Results indicated that for all subjects tested...

متن کاملSpatial channel interactions in cochlear implants.
The modern multi-channel cochlear implant is widely considered to be the most successful neural prosthesis owing to its ability to restore partial hearing to post-lingually deafened adults and to allow essentially normal language development in pre-lingually deafened children. However, the implant performance varies greatly in individuals and is still limited in background noise, tonal language...
متن کاملSpeech Perception in Children with Cochlear Implants
Cochlear implants provide access to the speech signal in children with hearing loss that often cannot benefit from acoustic hearing aids. However, despite the numerous positive results in pediatric cochlear implantation, published data still indicated a wide range of performance among implant recipients. Hence, a need to study the possible variables that can affect performance, could account fo...
متن کاملA Novel Channel Selection System in Cochlear Implants Using Artificial Neural Network
State-of-the-art speech processors in cochlear implants perform channel selection using a spectral maxima strategy. This strategy can lead to confusions when high frequency features are needed to discriminate between sounds. We present in this paper a novel channel selection strategy based upon pattern recognition which allows "smart" channel selections to be made. The proposed strategy is impl...
