Evaluation of Software for Self-Fitting of Hearing Aids by People With Hearing Loss

Sonova AG27 enrolled

Overview

The purpose of the study is to evaluate the efficacy of a prototype app for the self-fitting of hearing aids.

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.

Outcomes

Primary Outcomes

Change in speech perception after 30 days

The online Speech Perception Test developed by Blamey Saunders Hearing will be used to assess the effect of the intervention on speech perception.

Time frame: Day 1 and Day 30

Change in self-rated hearing ability after 30 days

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.

Time frame: Day 1 and Day 30

Softest sounds that can be heard

The intervention will be used to measure the softest sounds that can be heard at different tone frequencies.

Time frame: Day 1

Secondary Outcomes

Change in preferences for fitted settings and fitting method over 30 days

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.

Time frame: Day 1, Day 10, Day 20 and Day 30.

Change in experimental self-fitting phone app use over 30 days

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.

Time frame: Days 1-30
