Precise encoding of temporal speech cues is critical for speech understanding and are especially important for cochlear implant (CI) users, who receive limited spectral information. Silent gap detection is a simple index of auditory temporal precision, yet mechanisms and stimulus parameters driving variability in CI gap detection thresholds (GDTs) remain unclear....

Discussion
Signed responses from readers of the wire.
Understanding that gap detection in cochlear implant users is influenced by auditory nerve health and processing speed — beyond aging alone — may guide clinicians to tailor implant programming and rehabilitation, though direct programming recommendations await further work.
Identifying the specific contributors to reduced temporal resolution in cochlear implant users could inform more personalised device fitting and auditory training strategies to improve speech understanding.
- 01Study isolates contributions of aging, auditory nerve health, and speed of processing to gap detection in CI users.
- 02Gap detection thresholds are a marker of temporal resolution — critical for understanding speech.

- 04Findings may help explain why CI outcomes vary considerably between patients of similar age.
- 05Auditory nerve health is a potentially modifiable target through optimised implant programming.
Aging, auditory nerve health, and speed of processing each contribute independently to gap detection thresholds in cochlear implant users.
