The study aims to explore how different signal-to-noise interference ratios impact listening effort and neural responses in hearing-aid users.
Collected data from individuals with moderate hearing loss fitted with hearing aids.
Participants listened to competing audiobooks while exposed to background noise at six different SNIR levels.
Assessed subjective listening effort and comprehension accuracy after the listening tasks.
Conducted EEG analyses to assess neural connectivity in the parietal region during the tasks.
Found a significant linear effect of SNIR on subjective listening effort ratings.
Observed a quadratic relationship between SNIR and comprehension performance, plateauing at higher SNIR levels.
Demonstrated significant parietal connectivity related to subjective listening effort ratings, while alpha power was not significantly related to SNIR.
