Auditory Profile-based Hearing-aid Fitting: A Proof-of-concept study. <em>[under review]</em>.<br> <strong>[Preprint available in medRxiv:</strong> https://doi.org/10.1101/2020.04.14.20036459<strong>]</strong> Abstract <strong>Objective:</strong> The clinical characterization of hearing deficits for hearing-aid fitting purposes is typically based on the pure-tone audiogram only. In a previous study, a group of hearing-impaired listeners were tested using a comprehensive test battery designed to tap into different aspects of hearing. A data-driven analysis of the data yielded four clinically relevant patient subpopulations or “auditory profiles”. In the current study, profile-based hearing-aid settings were proposed and evaluated to explore their potential with respect to providing more targeted hearing-aid treatment. <strong>Design:</strong> Four candidate hearing-aid settings were implemented and evaluated by a subset of the participants tested previously. The evaluation consisted of multi-comparison preference ratings carried out in realistic sound scenarios. <strong>Results:</strong> Listeners belonging to different auditory profiles differed in terms of preference and favoured the targeted hearing-aid setting. <strong>Conclusion:</strong> The results of this proof-of-concept study support further investigations into a stratified, profile-based hearing-aid fitting with wearable hearing aids.
