Auditory Processing Disorder (APD) is defined as a disorder in recognition, discrimination, separation, grouping, localisation or ordering of sounds.AP evaluation of children with learning disorders has two goals:1) to rule out an auditory processing disorder (APD) as a contributing factor for impaired cognition and 2) to diagnose APD in children with learning disabilities, in order to ensure appropriate remediation.
46 children were evaluated for Auditory Processing Disorders. 40 of them were fully assessed in 2 sessions each. 6 were lost to follow-up. We applied the: a) Peripheral hearing testing: Otoscopy, PTA, Speech audiometry b) AP battery:, Speech in noise, Duration Pattern Sequence (DPS), Pitch Pattern Sequence (PPS), Random GAP. C) Speech in noise: normative data from our lab. D) DPS,PPS, Random GAP: Standardized tests (Auditec, St. Louis). E) Learning Disability battery: WISC-III, Language tests (phonemic synthesis, non-words).
22 (of 40) 55% are diagnosed with Auditory Processing Disorders (at least 1 of the AP tests is pathological.) All 22 children with APD are already receiving appropriate treatment according to their auditory processing deficits and are being followed up for their progress. APD management strategies include: 1. Signal enhancement strategies 2. Specific Auditory Training 3.Linguistic, cognitive, metacognitive and educational strategies
Identification of underlying specific auditory deficits in the heterogeneous group of LD children may indicate what remedial action is appropriate, since appropriate management of the auditory processing deficits may lead to improved auditory as well as reading skills.
