- ≥3 months post cochlear implant activation
Exclusion Criteria:
- Unable or unwilling to comply with the requirements of the clinical investigation as determined by the Investigator.
- Additional health factors, known to the investigator, that would prevent or restrict participation in the audiological evaluations.
- Investigator site personnel directly affiliated with this study and/or the investigator's 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 the other investigation was/is a Cochlear sponsored investigation and determined by the investigator or Sponsor to not impact this investigation).

Intervention / Treatment |
---|---|
Other: Investigational pre-processing algorithm/Standard of Care pre-processing algorithm
|
The algorithms act upon the digital audio signal received by the microphones and other sensors to enhance speech and attenuate noise prior to encoding the signal for delivery to a cochlear implant via the specified system.
Automatic Gain Control, SNR-NR, Forward Focus

Measure Description |
Time Frame |
---|---|---|
Australian Sentence Test in Noise (AuSTIN)
Time Frame: 1 day - Immediately post-screening
|
To determine whether the research algorithm provides non-inferior performance to the standard-of-care algorithm for sentences in noise using an adaptive sentence test in noise scores. Scoring: AuSTIN is scored as a Speech Reception Threshold (SRT), which reflects the volume of speech signal (in decibels, dB) relative to the background noise required for the subject to achieve 50% correct. For example, a score of 2dB SRT means the subject requires the speech to be 2dB louder than the background noise in order to correctly identify 50% of the target sentence. Range: -30dB to +30dB. Lower scores reflect a better outcome. |
