Hearing Outcomes With the Nucleus® 8 Sound Processor and Nucleus® 7 Sound Processor in Adult Veteran and Non-veteran Cochlear Implant Recipients
United States26 participantsStarted 2026-05
Plain-language summary
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.

Inclusion criteria
. Aged 18 years or older, at time of consent.
. Implanted with the CI600 Series (CI612, CI632, CI622, CI624), CI500 Series (CI512, CI532, CI522) or Freedom Series (CI24R(CA), CI24R(ST) CI24R(CS), CI24M, CI24RE(CA), CI24RE(ST), CI422) in the test ear.
. At least 18 active electrodes in the test ear.
. At least 6 months experience with a cochlear implant in the test ear.
. Able to score 20% or more at +10 dB SNR with CI alone on an S0N0 sentence in-noise test in the test ear.
. Pure-tone average unaided threshold (500 through 4000 Hz) ≥ 30 dB HL, in the contralateral ear.
. Candidate is a fluent speaker in the language used to assess speech perception performance.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

. Recipients with single-sided deafness as determined by the Investigator.
. Additional disabilities that would prevent participation in evaluations.
. Unrealistic expectations on the part of the subject, regarding the possible benefits, risks and limitations that are inherent to the procedures.
. Unable or unwilling to comply with the requirements of the clinical investigation as determined by the Investigator.
. Investigator site personnel directly affiliated with this study and/or their immediate families; immediate family is defined as a spouse, parent, child, or sibling.
. Cochlear employees or employees of Contract Research Organizations or contractors engaged by Cochlear for the purposes of this investigation.
. Current participation, or participation in another interventional clinical study/trial in the past 30 days, involving an investigational drug or device (unless Cochlear sponsored and determined by Investigator or Sponsor to not impact this investigation).
