Study: NCT06420037

Intervention type: DEVICE
Group type: EXPERIMENTAL
Intervention: Hearing aid feature adjustment (frequency compression) of the following hearing aids: Phonak Audéo Paradise/Lumity 70
Description: Upon enrollment, each participant will be allocated to one of three research groups and participants will remain unaware of their group assignment. This groups will undergo a slight modification, namely frequency compression turned off, to the basic setting.

Intervention: Audiological Assessment
Description: Three audiological tests are included: 1) Tympanometry to assess the middle ear status, 2) Pure-tone audiometry with headphone to evaluate the hearing thresholds, 3) Speech audiometry in free field to assess the ability to understand spoken sentences in quiet and in the presence of background noise.

Intervention: Questionnaires
Description: Three questionnaires are included:~1. The HAVICOP questionnaire to assess the hearing-related quality of life (Ceuleers, D., Baudonck, N., Keppler, H., Kestens, K., Dhooge, I., \& Degeest, S. (2023). Development of the hearing-related quality of life questionnaire for auditory-visual, cognitive and psychosocial functioning (hAVICOP). Journal of communication disorders, 101, 106291.)~2. the FAS (fatigue assessment scale) to assess how you usually feel~3. the EEAS (extended effort assessment scale) to assess how you experience listening in everyday life.
