Abstract
Objective: 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.
Design: 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.
Results: Listeners belonging to different auditory profiles differed in terms of preference and favoured the targeted hearing-aid setting.
Conclusion: The results of this proof-of-concept study support further investigations into a stratified, profile-based hearing-aid fitting with wearable hearing aids.

Description of the files:
- APBHAF_Audiofiles.zip: Audio files used in the SenseLabOnline environment. Each folder corresponds to one participant.
- APBHAF_MUSHA.xlsx: Raw Data of the MUSHA experiment.
- MUS_SoundScenes.mat: Mat file with a structure 1x9 MUS with the raw acoustic signals before processing with the hearing-aid simulator.
- CurrentMixture: matrix consisting of the simulated acoustic signal recorded by the 4 microphones of the hearing-aid satellites: 1) front-left, 2) back-left, 3) front-right, 4) back-right.
- CurrentAnchor: matrix consisting of the simulated acoustic signal recorded by the 4 microphones of the hearing-aid satellites: 1) front-left, 2) back-left, 3) front-right, 4) back-right. The Anchor is -6 dB SNR.
