This study concerns audiometric evaluation and prediction of hearing loss in the autistic child based on information derived from acoustic reflex thresholds. Two groups (autistic males and normal children) of five subjects each were utilized. Results indicated that the acoustic reflex method consistently predicted significantly higher hearing thresholds for autistic subjects than operant pure-tone audiometric procedures. Furthermore, the acoustic reflex thresholds were significantly less sensitive in the autistic group than in the normal group, suggesting that the acoustic reflex response is somehow altered in autistic individuals. These findings are consistent with earlier work which hypothesized that autistics, manifest an organic brain lesion which interferes with the propagation of auditory information.
