Wavelet analysis of auditory evoked potentials recording human vertex responses (Image analysis and multidmensional wavelet analysis)

Abstract

This paper describes the wavelet analysis of auditory evoked potentials, such as auditory brainstem responses (ABRs) and auditory steady-state responses (ASSRs). Because ABRs are examined using the peak amplitudes and latencies of waveforms in hearing diagnosis, one-dimensional discrete stationary wavelet analysis (DSWA) is beneficial for analyzing ABRs. Power spectrum analysis and phase coherence analysis using one-dimensional complex continuous wavelet analysis (CCWA) are useful for the detection of ASSRs because of their sinusoidal waveform configuration.
