Study Arms:
- Newly Implanted Group (Type: EXPERIMENTAL): HiRes 90K™ Advantage implant with HiFocus™ Mid-Scala electrode will be implanted in adults with partial deafness. Patients retaining considerable low frequency acoustic hearing after the surgery, will be fitted with the EAS sound processor.
- Existing Implanted Group (Type: EXPERIMENTAL): Adults unilaterally implanted with HiRes 90K™ Advantage implant with HiFocus™ Mid-Scala electrode with partial deafness will be fitted with the EAS sound processor.
- EAS Extended Use Arm (Type: EXPERIMENTAL): Adults who are unilaterally implanted with HiRes 90K™ Advantage implant with HiFocus™ Mid-Scala electrode with partial deafness and completed the 12 Month visit using the EAS sound processor in either the Newly Implanted Group or Existing Implanted Group.

Based on this trial design, predict the completion outcome and termination type (if applicable).
