The Study About the Reduction of the Stimulus Artifact Using PSR Filter

In order to reduce the stimulus artifact, which is contaminated in the initial segments of the transient evoked otoacoustic emission (TEOAE) and inhibited the detection of high frequency cochlear responses, an artifact reduction technique that draws on predictor-subtracter-restorer filter for TEOAE signal is firstly proposed. Compared with derived nonlinear response (DNLR) method, the result showed empirically that this proposed method not only reduced the stimulus artifact, but also reserved the useful information of TEOAE at high frequency
