Abstract: Recently the measurement of transient evoked otoacoustic emissions (TEOAEs) has been universally accepted as a noninvasive, objective method for the detection of cochlear damage. We present a computerized data preparation method which facilitates the comparison of several measurements of otoemissions for different stimuli. By comparing signals at different stimuli for corresponding time intervals it is possible to detect characteristic cochlear emissions at lower stimulus levels. Especially in case of ambiguous test results detecting typical emission waves by comparison helps to improve the reliability of TEOAE measurement.
