Conditions
Brief summary
The purpose of the study is to evaluate the efficacy of a prototype app for the self-fitting of hearing aids.
Detailed description
After being informed about the study and potential risks, clients giving written informed consent will be enrolled as participants. Each participant will use the app to self-fit and fine-tune the study aids over 30 days. Outcome measures include speech perception tests, questionnaires and the need for support with using the app. Own-aid performance is the reference, while unaided performance is the baseline.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in speech perception after 30 days | Day 1 and Day 30 | The online Speech Perception Test developed by Blamey Saunders Hearing will be used to assess the effect of the intervention on speech perception. |
| Change in self-rated hearing ability after 30 days | Day 1 and Day 30 | An expanded version of the Client Oriented Scale of Improvement questionnaire will be used to assess the effect of the intervention on self-rated hearing ability in different listening situations. |
| Softest sounds that can be heard | Day 1 | The intervention will be used to measure the softest sounds that can be heard at different tone frequencies. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in preferences for fitted settings and fitting method over 30 days | Day 1, Day 10, Day 20 and Day 30. | A custom questionnaire will be used to assess preferences for the fitted settings and fitting method of the intervention as these preferences evolve over time. |
| Change in experimental self-fitting phone app use over 30 days | Days 1-30 | The use of the experimental self-fitting phone app will be automatically logged every day to assess changes in how the app is used over time. |
