OR Subject with single-sided sensorineural deafness who is a candidate for Baha surgery.
Air conduction thresholds with a pure tone average PTA4 (mean of 0.5, 1, 2 and 3 kHz) of =
20 dB sensorineural hearing loss in the good ear OR subject who is indicated for an (Air
Conduction-Contralateral Routing of Signal (AC CROS) but-for some reason-cannot or will not
use an AC CROS.

- Previous experience from amplified sound through properly fitted amplification (for
example but not limited to Hearing aid, Contralateral Routing of Signal (CROS) device,
Bone conduction hearing device on softband).

Key exclusion criteria
- Uncontrolled diabetes as judged by the investigator.

- Condition that could jeopardise osseointegration and/or wound healing (e.g.
osteoporosis, psoriasis, long-term systemic use of corticosteroids) or condition that
may have an impact on the outcome of the investigation as judged by the investigator.

- Insufficient bone quality and quantity to support successful implant placement.

- Previous surgery and/or implantation with any bone conduction/active device on the
side to be implanted, which may jeopardise the implantation and use of the Osia 2
system, as judged by the investigator.

- Use of ototoxic drugs that could be harmful to the hearing, as judged by the
investigator.

- Unable to follow investigational procedures, e.g. to complete quality of life scales,
or unwilling to comply with the requirements of the clinical investigation as
determined by the investigator.

- Condition with a likely negative progression and/or with expected relapses
jeopardising general wellbeing and health-related quality of life as judged by the
investigator.

- Subject that has received radiotherapy in the area of implantation or is planned for
such radiotherapy during the study period.

- 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

- Currently participating, or participated within the last 30 days, in another
interventional clinical investigation involving an investigational drug or device.
