Popis: This study was undertaken to investigate the effects of click interstimulus interval (ISI) and sensation level (SL) on the short‐latency auditory‐evoked potential (AEP), and the relation of the AEP and the frequency‐following response (FFR). Continuous tones of 250 and 500 Hz and 0.1‐msec acoustic clicks with ISI's of 250, 70, 17, 8, 4, and 2 msec were employed as stimuli at SL's of 70, 50, 30, and 10 dB. Both ISI and SL affect the AEP in a similar manner. A reduction in either results in an increase in response latency and a diminution of response amplitude. The relative effects are shown in terms of isolatency and isopotential curves for wave V. As the ISI becomes very short, the AEP becomes similar in waveform amplitude and threshold characteristics to the FFR to continuous tones.
