Fig. 4. (A) Examples of auditory evoked potential (AEP) waveforms to stimuli of 4
kHz carrier frequency at various intensities (dB SPL). (B) Cross-correlation
functions (CCFs) between the corresponding waveforms and a standard AEP
waveform obtained at high (110 dB) stimulus intensity. CCFs are calibrated in
RMS values within a 10-ms window. Dots in B show CCF peak positions.
