Study Summary
The goal of this study is to improve music and speech perception for cochlear implant users. Presently, most cochlear implants discard the temporal fine structure of sound, which is information that is widely believed to contribute to both music and speech perception. The proposed work examines perceptual and physiological changes that occur once this information is provided to cochlear implant users in a clear and consistent manner.
Primary Outcome
Just-noticeable difference for pitch ranking based on stimulation cues. Pitch discrimination will be measured as provided independently by place and rate of cochlear implant stimulation, as well as in combination. Stimuli will be dual-electrode pulse trains, which probe place-pitch perception with greater resolution than possible with single-electrode stimulation. Two-alternative forced-choice procedures will be used in which participants judge which of two stimuli is higher in pitch. Frequency
