Many babies will only need the AOAE test, but it's common to have the AABR
As an example, the Joint Committee on Infant Hearing (JCIH) recommends the use of OAE or AABR for infants admitted to well-infant nurseries and AABR for infants admitted to the neonatal intensive care unit (NICU), while the Health Professions Council of South Africa's (HPCSA) position statement in 2007 recommended the use of AABR for infants who had been admitted to the NICU, and OAE for screening during immunisation visits at PHC clinics within the SA context.
5) were as follows: 75% (n = 18/24) reported using both distortion product otoacoustic emmissions (DPOAE) and AABR, and 13 of them indicated the additional use of at least one outer-ear or middle-ear screening measure, such as otoscopy, high-frequency (1 000 Hz probe tone) and acoustic reflex screening; 21% (n = 5/24) reported using DPOAE and AABR, with no use of outer and middle ear screening measures; 21% (n = 5/24) reported using either DPOAE or AABR; and 1 participant reported using only otoscopy and tympanometry for NIHS.
Of the 14 participants who screen in the NICU or at discharge from the NICU, 12 reported making use of AABR as one of the screening measures.
assesses auditory function from the eighth nerve through the auditory brainstem.
TEOAE had a significantly higher referral rate (6.5%) than the two-step protocol (4.7%) and AABR (3.2%).
In the two-step protocol, all infants receive a TEOAE screen and only those who fail the TEQAF screen go on to a AABR screen, which was approximately 20% in the study.
Predischarge costs for 1,500 births, which includes personnel, equipment, supplies, and program overhead, was lowest for TEOAE and highest for AABR (See table.)

Mehl and Thompson reported on the Colorado screening program that used either otoacoustic emissions or AABR. There were no false- negatives, and 41,796 infants were screened.
The 2 most commonly used technologies are AABRs and otoacoustic emissions.
