Summary
This early feasibility study aims to collect pilot data on impedance measurements in real-world environments and to collect real-world and difficult listening situations and the factors impacting this, reflecting situations the subjects encounter during their daily life outside of the clinic. Improving the monitoring of both aspects may lead to improvements in monitoring and personalising the fitting to optimise hearing outcomes for persons with a cochlear implant.
Eligibility Criteria
Inclusion Criteria
- Aged 18 years or older (no upper age limit).
- Implanted with CIC4-based implant with a Contour Advance, Slim Straight or Slim Modiolar electrode array with at least 6 months experience.
- Candidate is a fluent speaker in the language used to assess speech perception performance, as determined by the investigator.
- Willing and able to provide written informed consent.
Exclusion Criteria
- Score below 3 on the screening subset of questions from the Mobile Device Proficiency Questionnaire (digital literacy check).
- A failed ECE1 or ECE2 (i.e. flagged, open circuit or short circuit)
- Additional health factors, known to the investigator, that would prevent or restrict participation in the evaluations, including significant visual impairment and/or dexterity issues.
- 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 Organisations 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 the other investigation was/is a Cochlear sponsored investigation and determined by the investigator or Sponsor to not impact this investigation)
