Auditory late latency responses (ALLRs), signal-to-noise ratio − 50 (SNR-50), and scores of speech spatial and qualities questionnaire (SSQ) were measured three times over a period of 2 months of hearing aid use.Results:ALLRs showed a significant decrease in the P1 and N1 latency across the three measurements. Significant increase in the scores of SSQ and significant decrease in the SNR-50 were also found. The change in ALLRs did not correlate with change in scores of either SSQ or SNR-50.Conclusions:The study provides evidence for improvements in neural processing of auditory cortical areas with hearing aid acclimatization. The improvements seen in perceived benefit and speech perception are not related to the improvements in ALLRs. This is the first study in the domain with a younger group compared to the previous studies and the results show evidence for neural plasticity influencing hearing aid acclimatization benefits.  aSandeep Maruthy   aEuropean archives of oto-rhino-laryngology   uhttps://doi.org/10.1007/s00405-019-05303-0  cFJASyFJAS  c17763d17763
