Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adult cochlear implant users aged 18 and older.
✕Probably not a fit
Patients who are younger than 18 years or do not use cochlear implants may not benefit from this study.

What this trial studies
This study aims to enhance the ability of cochlear implant users to perceive music and speech by restoring the temporal fine structure of sound, which is often lost in conventional cochlear implants. The research investigates how cochlear implant users can learn to utilize this information when it is provided clearly and consistently. It focuses on two main aims: the impact of stimulation place and rate on pitch perception, and the effectiveness of dynamic-rate stimulation compared to traditional methods. The study employs a combination of perceptual learning, psychophysics, electrophysiology, and computational modeling to explore the plasticity of pitch perception in these users.
Why it matters
Potential benefit: If successful, this study could significantly improve the quality of life for cochlear implant users by enhancing their ability to perceive music and speech.
How similar studies have gone: While attempts have been made to restore temporal fine structure in cochlear implants, this approach is unique and has not been extensively tested in previous studies.
