Eligibility Criteria
Inclusion Criteria:
1. 18 years-of-age or older at the time of surgery.
2. Low-frequency threshold at 500 Hz ≤ 50 dB HL and high-frequency pure-tone average
(PTA), 2000-8000 Hz ≥ 65 dB HL in the ear to be implanted.
3. Pure-tone average (PTA) (0.5k, 1k, 2k Hz) > 30 dB HL in the contralateral ear.
4. CNC word recognition scores (mean of two lists) ≤ 60% in the ear to be implanted and ≤
80% in the contralateral ear.
5. English spoken as a primary language.
6. Willing and able to provide written informed consent.
Exclusion Criteria:
1. Individuals older than 70 years at the time of surgery.
2. Duration of severe to profound sensorineural hearing loss > 20 years per self-report.
3. Onset of sensorineural hearing loss, for the purpose of this study, prior to 5
years-of-age.
4. Ossification or any other cochlear anomaly that might prevent complete insertion of
the electrode array.
5. Conductive overlay of 15 dB or greater at two or more frequencies, in the range of 250
through 1000 Hz in the ear to be implanted.
6. Hearing loss of neural or central origin.
7. Diagnosis of Auditory Neuropathy.
8. Active middle-ear infection.
9. Medical or psychological conditions that contraindicate undergoing surgery as
determined by the Investigator.
10. Unrealistic expectations on the part of the subject, regarding the possible benefits,
risks, and limitations that are inherent to the device and/or procedure, as determined
by the Investigator.
11. Additional handicaps that would prevent or restrict participation in the audiological
evaluations as determined by the Investigator.
12. Unable or unwilling to comply with the requirements of the clinical investigation as
determined by the Investigator.
13. Investigator site personnel directly affiliated with this study and/or their immediate
family (spouse, parent, child, or sibling).
14. Cochlear employees or employees of a Contract Research Organization (CRO) or
contractors engaged by Cochlear for the purposes of this investigation.
15. Currently participating, or has participated in the last 30 days, in another
interventional clinical investigation/trial involving an investigational drug or
device.
