Listening in noise training in children with auditory processing disorder: exploring group and individual data

Purpose: The purpose of this study was to examine the impact of auditory training in noise on auditory behaviors and life habits in children with auditory processing disorder. Methods: Ten children with auditory processing disorder underwent an auditory training program in noise and six children with auditory processing disorder comprised a control group. Before and after training, participants were tested on sentence identification in noise and auditory evoked late latency responses. Participants teachers completed two questionnaires on children's auditory behaviors and life habits. Results: Participants were more tolerant to noise as the training sessions progressed. Significant between-group differences were found in P1 and N2 latency measures, independent of measurement time. The observed data trends suggest that some participants improved their performance on the sentence identification task in noise as well as on some electrophysiological parameters. No significant differences in questionnaire scores were found between groups or measurement times. However, one questionnaire showed significant between-group differences for certain questions. Conclusions: Listening in noise can improve with training for children with auditory processing disorder. However, this training program might be beneficial for some, but not all, children with auditory processing disorder. More data are needed to verify individual data trends.
