The aim of this study is to compare pass rates for two different hearing screening methods in well newborns as a function of age. Hearing screening tests were performed on 400 ears in 200 healthy newborn infants at the University of california-Irvine Medical Center. The screening methods used were automated auditory brainstem response (ABR) and click evoked otoacoustic emissions (EOAE). The infants' ages ranged from 5 to 120 h, with an average age of 24 h. Overall, 88.5% of ears passed the ABR screen, and 79% passed the EOAE screen. There was no significant difference in the ABR pass rate for infants aged 0-24 h of age as compared with infants aged > 24 h compared with the group aged 0-24 h (P < 0.01). Results are compared with earlier studies and implications for universal hearing screening are discussed.
