Influence of artifacts and pass/refer criteria on otoacoustic emission hearing screening


Schmuziger, N; Lodwig, A; Probst, R (2006). Influence of artifacts and pass/refer criteria on otoacoustic emission hearing screening. International Journal of Audiology, 45(2):67-73.

Abstract

A screening device for otoacoustic emission (OAE) testing was evaluated via measurements of click evoked OAEs (CEOAEs) and/or distortion product OAEs (DPOAEs) obtained in normally hearing young adults and newborns. Moreover, measurements were performed in a passive cavity and in ears with severe sensorineural hearing loss, in which the occurrence of a pass result was assumed to indicate artifacts. Different parameter settings were investigated. In comparison to normally hearing young adults, overall pass rates in newborns were similar using CEOAEs (93 to 100%), but lower using DPOAEs (65 to 95% vs. 83 to 100%). Pass rates in ears with severe hearing loss were 10% at 2 kHz, 13% at 3 kHz, and lower at other frequencies. Pass rates in the test cavity were generally low. The influence of test frequency on pass rates and calculations using computer simulation indicated the presence of artifacts. The discrimination of such artifacts from biological signals is difficult or impossible, and they may represent a serious problem for efficient OAE screening.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
