Background:
Otoacoustic emissions (OAE) are considered the main instrument of the Newborn Hearing Screening Program (NHSP).
Aim:
To analyze the OAE of newborns evaluated in the NHSP.
Method:
Transient evoked OAE recordings were captured in 1000 infants. The data were analyzed using the analysis of multivaried variance (Manova).
Results:
Reference tables were calculated for the over all OAE levels and for frequency bands, according to gender and ear. The duration of the exam in the nursery was shorter than in the clinic.
Conclusion:
The level of the OAE was influenced by gender and ear, except for 0,7kHz. However, there were no observed differences between neonates without and with auditory risk.
