Signal Processing Strategies for Cochlear Implants using Current Steering

TL;DR: It is confirmed that CI listeners’ voice perception deficit goes beyond poor perception of F0, and a potential common explanation not only for a number of deficits observed in CI listeners, such as voice identification and gender categorization, but also for competing speech perception.

TL;DR: The study showed that the binaural beamformer implemented in the Phonak Ambra hearing aid could be used in conjunction with a Harmony speech processor to produce substantial average improvements in SRT of 7.1 dB.

TL;DR: The challenge in getting a decent signal to the brain for users of cochlear implants (CIs) is described and the steps in achieving the present levels of performance are traced, and some possibilities for further improvements are mentioned.

TL;DR: Findings suggest that Fidelity120 supports small improvements in the perception of spectral speech cues in some Advanced Bionics CI users; however, many users show no clear benefit.

TL;DR: A broad class of up‐down methods used in psychoacoustics with due emphasis on the related problems of parameter estimation and the efficient placing of observations is described, including examples where conventional techniques are inapplicable.

TL;DR: It is shown that the newer extended data on human cadaver ears and from living animal preparations are quite well fit by the same basic function, which increases the function's value in plotting auditory data and in modeling concerned with speech and other bioacoustic signals.

TL;DR: The comparison of the new strategy and a standard clinical processor shows large improvements in the scores of speech reception tests for all subjects, which have important implications for the treatment of deafness and for minimal representations of speech at the auditory periphery.

TL;DR: This work synthesized stimuli that they call ‘auditory chimaeras’, which have the envelope of one sound and the fine structure of another, and shows that the envelope is most important for speech reception, and thefine structure is mostImportant for pitch perception and sound localization.
