The study about the reduction of the stimulus artifact using Predictor-Subtractor-Restorer (PSR) filter

In order to reduce the stimulus artifact, which is contaminated in the initial segments of Transient Evoked Otoacoustic Emissions (TEOAE) and inhibits the examination of high frequency cochlear responses, an artifact reduction technique that draws on PSR filter is proposed. Compared with Derived Nonlinear Response (DNLR) method, the result shows empirically that the proposed method not only reduce the stimulus artifact, but also reserve the useful information of TEOAE in the high frequency. This technique has high potential in clinical application for Transient Evoked Otoacoustic Emissions.
