Case study of children with suspected auditory processing disorder

Objective: To introduce methods of central auditory processing tests, study the principle of diagnosis and management of suspected auditory processing disorder. Methods: Three children are presented as case studies. Conducting audiological tests, educational psychology tests, speech pathology assessment and central auditory processing assessment. Results: All performed more than 5 standard deviations below the mean normative data score for their age group on both the Random Gap Detection Test, and the spatial advantage measure of the newly developed Listening in Spatialized Noise test (LISN®). The children were also greater than 2 standard deviations below the mean on the LISN high-cue SNR. Conclusion: The central auditory processing test battery revealed that all three children had deficits in binaural processing. These children would benefit from an improved signal-to-noise ratio in the classroom, applying auditory closure training, auditory localization and discrimination training, top-down language processing skills training.6 page(s
