The study examined listening effort (LE) in adults with hearing aids (HAs) and normal hearing using the Extended Effort Assessment Scale (EEAS). Participants self-assessed their LE in daily life situations. The study found that LE in quiet and LE in noise were separate constructs, with HA experience being the most influential factor. Better ear hearing threshold and ear asymmetry also contributed to LE. LE in noise was more dependent on HA experience, while LE in quiet was more influenced by hearing thresholds. HA experience reduced LE in noise over time, except in participants with at least 24 months of HA experience. The EEAS provides a comprehensive assessment of LE in different situations based on HA experience and hearing thresholds.
