Present-day cochlear implants demonstrate remarkable speech understanding performance
despite the use of non-optimized coding strategies concerning the transmission of tonal …

The aims of this paper are to (i) provide a brief history of cochlear implants;(ii) present a
status report on the current state of implant engineering and the levels of speech …

In the past 30 years, cochlear implantation has changed from being an experimental
procedure to representing the standard of care. Advances in processing strategies, implant …

While new electrode designs allow deeper insertion and wider coverage in the cochlea,
there is still considerable variation in the insertion depth of the electrode array among …

Abstract Using long Med-El Combi40+ electrode arrays, it is now possible to cover the whole
range of the cochlea, up to about two turns. Such insertion depths have received little …

In normal hearing, the pitch of an acoustic tone can theoretically be encoded by either the
place of stimulation in the cochlea or the corresponding rate of vibration. Thus spectral …

Objectives: This review examines evidence for potential benefits of using cochlear implant
electrodes that extend into the apical regions of the cochlea. Most cochlear implant systems …

Conclusion. Deeply inserted electrodes offer the possibility that apical stimulation may
improve speech performances. Therefore, deep insertion is reasonable and should be …

The relationship between the place of electrical stimulation from a cochlear implant and the
corresponding perceived pitch remains uncertain. Previous studies have estimated what the …

Eight cochlear implant users with near-normal hearing in their non-implanted ear compared
pitch percepts for pulsatile electric and acoustic pure-tone stimuli presented to the two ears …
