A microcomputer-based system for auditory evoked potentials

We have been using a microprocessor/microcomputer-based system which affords flexibility in the recording of neuroaudiologic and neurophysiologic data. To date, we have used it to record auditory sensory and neural events. Data such as spontaneous oto-acoustic emissions, evoked oto-acoustic emissions, compound action potentials, and auditory brain-stem responses can be recorded, displayed and analysed. The system hardware is configured from commercially available and 'off-the-shelf' components. The software which directs stimulus generation, data recording, data display and analysis is all written in compiled BASIC or C. A hard-disk organizational scheme has also been developed to permit ease in categorizing, storing, and using in-house or commercially available systems, utility and applications software.
