Trial Summary

What is the purpose of this trial?

The purpose of this study is to understand performance with a cochlear implant. The long-term goals of this research are to improve sound perception with cochlear implants and to better understand the functioning of the auditory system. Information from individuals with and without cochlear implants will be compared.

Eligibility Criteria

This trial is for children and adults with cochlear implants implanted before age 2, those who have some hearing left with aids, or normal hearing. It's open to ages 7-35 if pre-lingually implanted and 18+ for post-lingual implantation or normal hearing. Post-lingually implanted children cannot participate.

Inclusion Criteria

I am 7 or older and got a cochlear implant before age 2, or I can hear with aids or normally.

I am 18 or older with either a cochlear implant received after learning to speak or normal hearing.

I am between 18 and 35 years old and received my implant before I could speak.

Exclusion Criteria

Children who got a cochlear implant after they learned to speak.

Interventions

Cochlear Implant (Procedure)
Electric-only Spectral Resolution (Behavioural Intervention)
Modulation Detection Threshold (MDT) and Gap Detection Tasks (Behavioural Intervention)
Single-Electrode Pulse Train (Behavioural Intervention)
Sound Coding Strategy (Behavioural Intervention)

Trial OverviewThe study tests how different sound coding strategies in cochlear implants affect auditory performance. Participants will try electric-only spectral resolution methods and single-electrode pulse trains to see which improves sound perception.
