简要总结
The purpose of this study is to investigate speech understanding in simulated reverberant environments with MED-EL cochlear implant recipients.
详细描述
The study will determine if electrode length and coding strategy effect performance. The investigator will also study performance over time with new recipients.

研究组 & 干预措施
Current recipient of a Med-El cochlear implant
Participants who have received a MED-EL cochlear implant as a standard of care for treatment of hearing loss. Participants are tested at one time point with a simulated reverberant environment.
干预措施: Simulated reverberant environment (Other)
Future Med-El Recipient
Cochlear implant candidates not yet implanted and chose Med-El device as standard of care for treatment of hearing loss. Participants are tested at 3 time points over 6 months in a simulated reverberant environment.
干预措施: Simulated reverberant environment (Other)
结局指标

Coding strategy
时间窗: Two hours
Speech scores, in percent correct, recorded from simulated reverberant speech tests will be compared between fine structure and envelope coding strategies.
Speech Performance
时间窗: Up to six months
Speech performance recorded as percent correct compared to different electrode lengths.
