This study aims to optimize music listening quality for 66 hearing aid users (33 musicians and 33 non-musician music enthusiasts) by developing a dedicated "Music Program" based on individual frequency preference profiles. We will evaluate the program's efficacy by comparing listening quality and emotional response scores against standard settings, while also investigating correlations with music reward sensitivity. We hypothesize that the customized program will yield significant improvements, with a more pronounced benefit observed in the musician group.
Aged 18 years or older,
Fitted with hearing aids for at least 6 months,
Reporting dissatisfaction with music listening while using their hearing aids.
Asymmetric hearing loss (pure-tone audiometry showing a difference between the two ears > 15 dB)

Musical listening quality preference test
Other interventionPreference test to determine their Preferred Frequency Profile (PFP). The gain characteristics of the PFP will be added to the hearing aids' Main Program, thereby creating a dedicated Music Program.
Comparison of scores obtained using the Davies-Venn validated quality ranking questionnaire between the Main Program and the Music Program.
