Audiologists managing cochlear implant fittings should note that electrode deactivation may affect speech perception outcomes; however, the study design (unspecified controls) means clinical guidance should await replication in larger prospective studies.
Electrode deactivation is a common clinical strategy to improve cochlear implant performance, and understanding its perceptual and electrophysiological consequences is essential for optimising device programming.
- 01Electrode deactivation is a routine CI programming tool used to reduce channel interaction and improve sound clarity.
- 02Study assessed speech recognition in both quiet and noisy listening conditions after electrode deactivation.
- 03Objective electrophysiological measures (e.g., neural responses) were included alongside perceptual tests.
- 04Findings have direct relevance to audiologists and CI programmers making deactivation decisions.
