Bivariate correlations between N2 amplitude at T4 and the change in N2 amplitude between T2 and T4 with self-perceived improvement in everyday auditory communication, assessed via SSQ-B1–3 did not achieve statistical significance but showed a trend for a moderate negative correlation between N2 amplitude at T4 and the improvement of speech comprehension (SSQ-B1: r = −0.471, p = 0.076) and localization (SSQ-B2: r = −0.494, p = 0.061) recorded at the T4 assessment.
