e have established an experimental audio-visual stimulator that can manage 8 kinds of stimuli as a combination of sound resource files and PICT files using a personal computer (http: //www. urchin. co. jp). In this study we tested the stimulator for use in the auto-BAEP examination to obtain the IL curve that may be helpful for the diagnosis of hearing impairment deriving from sensorineural or conductive disorder. Latencies for wave-I and wave-V were detected using the autopeak scanning software (Brain Functions Lab Inc. http: //home. ksp. or. jp/bfl). These data were entered in the spreadsheet program and a graph like the IL curve was produced using macro functions. Finally, we obtained more useful results than Argo II, although skillful computer manipulation was required. It will now be necessary to develop our system to enable easier access and availability for actual clinical use.
