Abstract:

The patent relates to a hearing threshold level measuring apparatus for automatically determining testing hearing level in each ear and processing the test scores for either manual or automatic readout. A predetermined number of tone bursts varied randomly from one to four in each test sequence and automatically decreased in level. The subject is provided with a response panel containing pushbuttons labelled one through four. The subjects hearing threshold is then determined from his pushbutton responses to his correct burst tone counts.
