[Results of a study of the presence of spontaneous otoacoustic emissions in the newborn].
An otoacoustic emission is that part of sound that can be detected in the ear canal and is produced by the physiological cochlear activity involved in the auditive process. Some people have spontaneous oto-emissions (SOAE), which are emissions that can be registered without any stimulus. These are normal functional sounds of some cochleae. he aim of this study was to assess the presence of SOAE in newborns, as well as to study its incidence and relationship with the auditive process. The number of tested neonated was 364, 209 of whom had at least one ear with SOAE+ (57.4%). It was possible to do a bilateral test in only 324 newborns, 114 of whom had SOAE+ in both ears (35.18%). The total number of ears tested was 961 and in 453 of these a SOAE+ was detected (47.1%). This high incidence of SOAE corresponds to a very good cochlear condition compared to that of older people.
