title: Audiometric evaluation of infants 12-18 months of age.
abstract: Behavioral observation audiometry in conjunction with acoustic impedance studies have infrequently been evaluated in the 12-18 month infant population. Seventy-three infants from the neonatal registry had audiological evaluations performed consisting of speech detection and hearing threshold levels, as well as acoustic impedance studies. Complete audiometric results were obtained from 75% (55) of infants during the initial audiologic evaluation; 73% (53) provided binaural tympanograms. Only 50% of the patients cooperated for all four frequencies attempted on acoustic reflex studies with a 4% incidence of absent reflexes. Impedance studies confirmed audiometric findings in 77% of the infants evaluated.
