They completed two tests involving word and sentence recognition tasks, with accuracy and pupil diameter changes serving as indicators of listening effort and cognitive resource allocation. The main pupillary indices calculated and analyzed were baseline pupil diameter, peak value, and mean diameter.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The results showed that auditory threshold and signal\u2010to\u2010noise ratio (SNR) significantly influenced the accuracy of behavior. Pupillometry results for selective attention revealed a progressive increase in pupil diameter in the SSD group after the alert period of listening, with levels significantly higher than that of the NH group. During working memory tasks, participants with SSD demonstrated an initial increase in pupil diameter, followed by a decline throughout the task, suggesting persistent cognitive strain and potential fatigue.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Patients with SSD exert greater listening effort during daily communication.
