Individual electrode-nerve interfaces cause the wide variability in CI outcomes

Evidence

One reason that can explain this variability is the CI user’s individual electrode nerve interface which can impact the spectral resolution they can achieve. Spectral resolution has been reported to be related to vowel and consonant recognition in CI listeners. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1819
