Interventions

  • Nucleus 7 Sound Processor — DEVICE
    While the user can turn ForwardFocus on from any program in the Nucleus 7 Sound Processor, for the duration of this study, SCAN will be used as the default program and ForwardFocus will be turned on for testing. This setting will be referred to as SCAN ForwardFocus (SCAN FF).
  • Nucleus 8 Sound Processor — DEVICE
    Nucleus 8 Sound Processor will be used with the SCAN 2 ForwardFocus (SCAN 2 FF) program to evaluate speech performance.

Study Details

The main purpose of this study is to understand how well a noise reduction feature called ForwardFocus works when used with two different sound processors: the Nucleus® 8 Sound Processor and the Nucleus® 7 Sound Processor, in adults with cochlear implants. The study will include two groups of adult cochlear implant recipients: veterans and non-veterans. Comparing these groups will help researchers understand how these sound processors perform in veteran populations as well as the broader adult cochlear implant community. Participants will use each sound processor and then take part in speech understanding tests in background noise. They will also complete questionnaires about their listening experiences with each processor.
