Hearing Outcomes With the Nucleus® 8 Sound Processor and Nucleus® 7 Sound Processor in Adult Veteran and Non-veteran Cochlear Implant Recipients (SALUTE)

6. mai 2026 oppdatert av: Cochlear

A Post-market Interventional, Prospective, Open-label, Multi-center, Clinical Investigation of Hearing Outcomes With the Nucleus 8 Sound Processor and Nucleus 7 Sound Processor in Adult Veteran and Non-veteran Cochlear Implant Recipients

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.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Eksperimentell: Veterans
Enhet: Nucleus 7 Sound Processor
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).
Enhet: Nucleus 8 Sound Processor
Nucleus 8 Sound Processor will be used with the SCAN 2 ForwardFocus (SCAN 2 FF) program to evaluate speech performance.
Eksperimentell: Non-veterans
Enhet: Nucleus 7 Sound Processor
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).
Enhet: Nucleus 8 Sound Processor
Nucleus 8 Sound Processor will be used with the SCAN 2 ForwardFocus (SCAN 2 FF) program to evaluate speech performance.

Hva måler studien?

Primære resultatmål

Resultatmål
Tiltaksbeskrivelse
Tidsramme
Paired difference in AzBio percent correct in noise between the Nucleus 8 Sound Processor using the SCAN 2 FF program and the Nucleus 7 Sound Processor using the SCAN FF program at a fixed signal-to-noise ratio in the S0N90 spatial configuration
Tidsramme: Week 2 and week 4
The AzBio sentence test is a validated test used to assess open-set sentence recognition. AzBio sentences are spoken in a conversational style with limited contextual cues that the listener can use to predict unintelligible words.
