ABSTRACT:
A microprocessor-based audiometer for use with children. A color visual display unit is used to display an image digitally stored in memory or on disk drive to attract the childs attention and hold its concentration during testing.
The child activates a response switch upon detecting the tones produced by audiometer to the generator. Correct responses are reinforced by progressive alteration of the displayed image to increasingly desirable states.
