PURPOSE:
to assess the sensitivity and specificity of an automated Transient Evoked Otoacoustic Emissions equipment using narrow band stimulus.
METHODS:
the hearing screening results of 300 newborns were analyzed. A portable automated equipment was used with narrow band stimulus to conduct the Transient Evoked Otoacoustic Emissions. All newborns were also submitted to the Brainstem Auditory Evoked Potentials using 100μs-duration click stimuli, which was considered the gold standard test.
RESULTS:
the proportion of "pass" results in the neonatal hearing screening was 90.7%. Considering the gold standard results, it was observed a false-positive rate of 9%. The Transient Evoked Otoacoustic Emissions with narrow band stimulus presented sensitivity of 100% and specificity of 92%.
CONCLUSION:
the narrow band stimulus was efficient enough to be used in neonatal hearing screening programs.
