    OBJECTIVE: Determine the functioning of the efferent auditory system in premature newborns with intraventricular hemorrhage. METHOD: The study group was composed of 22 newborns with intraventricular hemorrhage and the control group was composed of 22 newborns without intraventricular hemorrhage, matched to the study group for gestational age, correct gestational age and sex. The groups were submitted to the study of otoacoustic emissions evoked by a transient stimulus and suppression in otoacoustic emissions (equipment ILOv6Otodynamics Ltda®) and the study of the auditory evoked potential with and without contralateral noise (equipment SmartEPIntelligent Hearing Systems®). RESULTS: Newborns with intraventricular hemorrhage exhibited a higher occurrence of central hearing alteration as well as a greater occurrence of the absence of the suppression in otoacoustic emissions and auditory evoked potential compared to the newborns without this condition. An association was found between central hearing alteration and a lower occurrence of suppression. Agreement was found between the suppression test on otoacoustic emissions and the suppression test on latency of the auditory evoked potential. CONCLUSION: Premature newborns with intraventricular hemorrhage have a greater occurrence of functional abnormality of the afferent auditory system, which can be effectively identified through an evaluation of the suppression of otoacoustic emissions evoked by a transient stimulus and the latency in the brainstem auditory evoked potential.
