Hearing aid feature profiles: The success of rehabilitation
We recently developed a method to objectively classify hearing aids, using technical data (e.g., compression, noise reduction, etc.) from over 3900 different devices. This yielded hearing aid subgroups called ‘modalities’, that were characterized as distinct feature profiles, independent of manufacturer or type. Our present study aims to combine these objectively defined modalities with audiologically relevant rehabilitation needs, using data including audiological diagnostic tests and two questionnaires for subjective ratings. We investigated which hearing aid modalities contribute to successful rehabilitation results, and to which extent these modalities can be associated with specific rehabilitation needs. Our results indicate that more adjustable hearing feature channels or levels do not necessarily lead to better rehabilitation results.
