An automated microcomputer based electric response audiometry system for machine scoring of auditory evoked potentials.

The system described is based on a Nascom 2, 8-bit microcomputer with a Z80A processor running at 4 MHz and 32K RAM. The main functions are: measurement of recording electrode contact impedance; generation of the auditory click stimulus; signal recording and averaging; mathematical scoring of the averaged waveforms; printer output of the response and threshold scores.
