Signal analysis of the auditory evoked potential (AEP) has been the interesting field in biomedicine and signal processing for a long time. Recent advances in the analytic method of AEP are summed up in this paper. Seven methods, including spectral analysis, adaptive filtering, wavelet transform, chaos theory, artificial neutral network, regularization, and independent component analysis are mainly introduced. All of them are promising for extracting the signal with less stimulation and adequate quality, and for displaying their efficient application in the analysis of AEP.
