Missing efferent benefits may explain cochlear-implant users’ speech-in-noise deficits

Evidence

The potential benefits attributed here to the contralateral MOCR are unavailable to current CI users and this might explain part of their impaired performance understanding speech in challenging environments. The present results suggest that the MOC processor, or a version of it, might improve CI performance. The MOC strategy may also be adapted for use with bilateral hearing aids. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1939

Categorization

• QUESTION: Whether replicating the MOCR computationally genuinely restores cocktail-party abilities in real CI users remains unconfirmed behaviorally—worth chasing the follow-up trials.
• corroborated: 3 independent passages support this claim — Dijk, Pim van, Physiology, Psychoacoustics and…, 1939
• XREF: connects to: Lacking MOC gain control partly explains CI users’ poor speech-in-noise performance; Cochlear-implant users show no sensitivity to inherent noise envelope fluctuations; Broader cochlear filtering reduces low-frequency noise fluctuations, explaining lost masking release — Dijk, Pim van, Physiology, Psychoacoustics and…, 2161 (+2 more)
