Introduction:
The acceptance of universal newborn hearing screening has been affected by the availability of an accurate, cost-effective tool. Transient evoked otoacoustic emission (TEOAE) procedures have been used successfully in hospital-based programs. A modified TEOAE method, using a narrow band signal, may be capable of maintaining accuracy while reducing test time. A comparison between a simplified narrow band TEOAE screening device (ILO1088-Echosensor) and the standard ILO88 Quickscreen mode was initiated in this study.
Methods:
One thousand ears of newborns in a normal nursery were tested using both devices.
Results:
Results demonstrated that there was good agreement between the two devices. The possibility that the 5.9% discrepancy between the two screeners may be related to restrictions in the protocol that prohibited calibrating or refitting the probe during the test should be explored.
Discussion:
The ILO1088 automated screener demonstrated good potential as a quick, accurate hearing screening device for newborns with the potential of reducing screener training and the need for off-line interpretation of the results when employed in a universal program.
