Abstract

Currently, there is a paucity of research regarding the differences between newborn hearing screening devices. The purpose of this study was to compare four such devices, the Bio-Logic AuDX, the Grason-Stadler GSI 70, the Madsen EchoScreen and the Otodynamics ILO 88. Two of the screeners compared were distortion product otoacoustic emission (DPOAE) devices and two were transient evoked otoacoustic emission (TEOAE) devices. The AuDX, the GSI 70, and the EchoScreen are all automated pass/fail hearing screeners and were compared to the ILO 88, which is non-automated. The devices chosen are widely marketed to hospitals for the implementation of newborn hearing screening programs. The outcomes, performance, and protocols of the devices were evaluated by screening 100 healthy newborns at Cox Health Systems in Springfield, Missouri. Each baby recruited into the study received four complete hearing screenings each; one for every screening device included in the study. A strong pass/fail agreement was shown between ILO 88 to the AuDX and the EchoScreen. The GSI 70 did not have a strong of a pass/fail agreement with the ILO 88. Specifically, the GSI 70 tended to fail approximately a third of the babies that were passed by the ILO 88.
