Abstract：Multi-rate steady-state averaging deconvolution (MSAD) is a newly developed method to restore the transient auditory evoked-potential (AEP) from the auditory steady-state responses (ASSRs) based on superposition hypothesis. This method requires that the variation of stimulus rates impose no substance influence on the response so that the model is applicable and viable. In this study, we recorded eight ASSRs from 20 subjects of 40-Hz average rate (from 27.2 Hz to 57.1 Hz), from which the transient AEP can be derived by the MSAD method. The AEP was then used to synthesize the ASSRs at the same recording rates. By comparing them with the recorded ASSRs, we examined the differences on the featured waves and the ASSR morphology. Results showed the peak-peak amplitudes of V-Na and the latencies of wave-Vs were close, and no statistic difference between recorded ASSR and synthetic ASSR at 36.8 and 39.1 Hz, whereas the minimum relative error of 7.95% was achieved at 36.8 Hz ASSR. It can be concluded that the stimulus rate has little effect on the responses within these range, which justifies the applicability of the MSAD method.
