evidence indicates that false-positive hearing screen results do not cause term general parental anxiety and that mothers who have the knowledge base to understand the context of a refer result experience much less anxiety. DPOAE screening DPOAEs are used less frequently than TEOAEs in newborn hearing screening. Although DPOAEs span a greater frequency range and are generally more robust in the presence of electrophysiological noise, there are problems in specifying a universally acceptable pass/refer criteria for the screen. A single study identifies a pass/fail criteria, with little identifiable data in the area since. While some evidence suggests that DPOAEs have a pass rate of 77.4%, other research has found false-positive rates ranging from 11.0% to 35.0%. One study reported implications for both the cost of consumables required for AOAE screening and parental anxiety. The reason that DPOAEs are not widely implemented is the unavailability of research data specifying the pass criteria to be utilised. Variability in pass and refer rates with differing pass criteria indicates the need for standardisation, particularly when implemented in newborn hearing screening programmes. A renowned expert in OAEs noted that DPOAEs are collected over a much wider range of stimulus intensities and a range of stimulus intensity ratios. This strongly affects sensitivity and specificity, so the volume of data on any particular stimulus combination is small. While there is validity in performing DPOAEs, it has been stated that are no sufficiently well-established criteria for ‘There DPOAEs that would allow DPOAEs to replace TEOAEs in Newborn Hearing Screening Programs without significant risk of a change in current specificity and sensitivity’. For this reason, this technique is not ideal for newborn hearing screening programmes until such data is available. The interpretation of DPOAE results for a neonate should include age-related differences in DPOAE pass rates for low-frequency and high-frequency information. Implications for detection of ANSD Detection of ANSD disorders utilising AOAE regimes is not possible. The OAE indicates cochlear function only, at the level of the outer hair cell. The OAE does not assess auditory function beyond the level of the cochlear and for this reason ANSD cannot be detected. Approximately 10.0% of all children diagnosed with a permanent hearing impairment have ANSD, . While NICU admission is a risk
