Verbesserte Auswertbarkeit transitorisch evozierter otoakustischer Emissionen durch Korrelationsfilterung
1993
Hearing screening as well as evaluation of cochlear function under therapy with ototoxic agents or patients with various diseases is increasingly done by registration of transient evoked otoacoustic emissions (TEOAE). Usually the standard system ILO 88 Otodynamic Analyser is used, where until now emissions were analyzed subjectively. However, evaluation of signals may be difficult mainly in the hearing threshold area. In this article we describe a method to mathematically analyze registered emissions by correlation-filtering. This allows to better identify small specific responses, to further increase the sensitivity of TEOAE, and offers a more objective means for audiologic diagnoses.

BACKGROUND The necessity of screening examinations in newborns today cannot be denied. Up to now, it has only been achieved in a few countries to introduce a general hearing screening for newborns. METHODS We examined 100 newborns (200 ears) at their third day of life. All ears were evaluated with the TEOAE-screening-device ECHOSCREEN. In addition, we carried out BERA screening examinations with the ALGO PORTABLE or with the EVOFLASH on 100 of these 200 ears. As a reference method, we utilized TEOAE-examinations with the ILO-88 for all ears. RESULTS 4.5% of the 200 ears examined with the ECHOSCREEN were conspicuous due to accumulation of earwax problems. With the ALGO-system, none of the ea…
Newborn hearing-screening project using transient evoked otoacoustic emissions: western sicily experience
2006
Summary Objective To study the incidence of congenital sensorineural hearing loss in all newborns introducing a screen test with a protocol no expensive, with a good “screen sensitivity” that could let an earlier identification of hearing impairment beginning early intervention by 2 months of age and increasing the probability of having language development within the normal range of development. Methods The study was conducted in Sciacca hospital from the beginning of 2003 to our days and was carried out with transient evoked otoacoustic emission using the criteria for PASS or RETEST and considering eventual prenatal and perinatal risk factors. All the newborns were divided into four group…
