The significance of acoustic admittance procedures in the audiologic evaluation of multiply-handicapped children.
The specific contribution of admittance procedures in the diagnosis of hearing impairment was studied in a group of 53 handicapped children. The value of admittance procedures was assessed in relation to that of otoscopy and pure tone audiometry. Admittance procedures and otoscopy were successfully performed in all but one of the children and indicated conductive pathology in about 40% of the subjects, whereas pure tone audiometry was not feasible or inconclusive in 30.2% of the subjects. In 5.7% of the subjects admittance procedures proved the only diagnostic tool.
