[Definition of normal criteria of provoked otoacoustic emission in the newborn infant].

Evoked otoacoustic emissions (EOE) were recorded with ILO88 in a group of 254 neonates (n = 508 ears) in order to determine the normative data. In this study, it was found that: (i) the mean EOE amplitude was 20.2 dB SPL, (ii) the EOE amplitude of the right ear was significantly higher than those of the left ear, (iii) the mean time necessary to record EOE in both ears was around three minutes, and (iv) EOE spectrum was large (mean = 638-5,611 Hertz). These data permit to precise the clinical interest of EOE for screening auditory function in neonates.
