Encoding Temporal Fine Structure for Cochlear Implants

NCT04708717 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 24

No results posted yet for this 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.

Conditions

Interventions

BEHAVIORAL

Stimulation Rate

Psychophysical training listening to stimulation rate as a cue for auditory pitch perception. The intervention is the listening rehabilitative exercises. Exercises are completed daily as 30-minute sessions for 2 weeks.

BEHAVIORAL

Electrode Location

Psychophysical training listening to electrode location as a cue for auditory pitch perception. The intervention is the listening rehabilitative exercises. Exercises are completed daily as 30-minute sessions for 2 weeks.
