Universal neonatal hearing screening has been done in two different maternity hospitals since 2001 continuously. In one of these two hospitals the number of high risk births was distinctively higher because of a neonatological emphasis of the department. As screening method for all early- and newborns measurement of otoacoustic emissions had been used (DPOAE – GSI 70 Grason & Stadler). After insecure results of the first DPOAE-screening the investigation had been repeated. If again pathological results occurred a pedaudiological diagnostic started with special emphasis on measurement of brainstem evoked response audiometry (BERA). Altogether 2900 newborns had been investigated. 15 % of those underwent a DPOEA-follow-up screen. The recall-rate for an BERA-testing lied around 1,5 %. Three out of 1000 newborns had a hearing impairment that needed special management. Those results confirm the estimated rate of prevalence. A good acceptance of screening and follow up could be recognized. The registration of otoacoustic emissions is well suited for early discovery of hearing impairment in newborns and helps to start pedaudiological diagnostic and therapy early.
