Abstract
The measured Distortion Product Otoacoustic Emissions (DPOAE) signals are always contaminated with stimulus-induced artifact and relatively high level of noise, which impose an limitation to the measuring speed. In this work, an adaptive filtering scheme is illustrated for the extraction of the DPOAE. Simulation shows that the artifact can be removed effectively and that the signal-to-noise ratio (SNR) can be improved significantly
