Actual date on which the first participant was enrolled.

This study focuses on evaluating a new device called the Osia 3 Sound Processor, which is used to help people with certain types of hearing loss, including mixed hearing loss, conductive hearing loss, or single-sided deafness. The aim is to determine whether this new sound processor provides better hearing performance and sound quality compared to the earlier model, the Osia 2 Sound Processor. This research is important because it could lead to improved hearing solutions for adults with these specific hearing challenges, potentially enhancing their quality of life by providing clearer and better sound experiences. Participants in the study will take part in speech performance tests, which will measure how well they can hear and understand speech in both quiet and noisy environments. They will also complete a questionnaire to share their personal experiences and satisfaction with the sound quality of the device. These evaluations help researchers determine if the Osia 3 Sound Processor offers superior performance to the previous model, contributing valuable information for improving hearing aid technology.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

29 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.



Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.

Criteria

Inclusion Criteria: * Implanted with a Cochlear Osia Implant (OSI100, OSI200, OSI300) * Conductive or mixed hearing loss in the implanted ear. Bone conduction thresholds up to 65 dB HL (up to 40 dB HL at 0.5 kHz, up to 55 dB HL at 1kHz and up to 65 dB HL at 2 and 4 kHz) or Single-Sided Deafness in the implanted ear. The pure tone average air conduction hearing thresholds of the hearing ear should be better than or equal to 20 dB HL (measured at 0.5, 1, 2 and, 3 kHz). * Aged 18 years or older, at time of consent. * Minimum experience of 1 month with the Osia 2 Sound Processor. * Fluent speaker in the language used to assess speech perception performance. * Willing and able to provide written informed consent. Exclusion Criteria: * Ongoing infection at or around the sound processor area. * Bilaterally implanted with a Cochlear Osia Implant. * Unable or unwilling to comply with the requirements of the clinical investigation as determined by the Investigator. * Use of ototoxic drugs that could be harmful to the hearing, as judged 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).

Treatment Groups
Study Objectives

2 intervention groups are designated in this study

This study does not include a placebo group 

Treatment Groups

Group I

Active Comparator
Participants randomized to group 1 will first receive a study Osia 2 Sound Processor to use at home for 1-2 weeks, before returning to the clinic to complete various assessments. These participants will then switch to the Osia 3 Sound Processor and complete the same protocol.

Group II

Experimental
Participants randomized to group 2 will first receive a Osia 3 Sound Processor to use at home for 1-2 weeks, before returning to the clinic to complete various assessments. These participants will then switch to the Osia 2 Sound Processor and complete the same protocol.
