A microprocessor audiometer for industrial hearing conservation programs
The MI-7000 is a microprocessor-controlled screening audiometer designed specifically for use in industrial hearing conservation programs. Both flexible and easy to use, it can be programmed to meet the demands of very large-scale programs where extensive demographic data must be collected, stored, printed, and downloaded with threshold values to a computer database. Yet it can be quickly reprogrammed to allow the operator to press one button to start and print a completed test with no further data entry or control manipulations. Programmed options are battery-backed and remain in effect until changed by the operator. Tones are generated and controlled entirely by digital circuits, allowing the output levels of the MI-7000 to be adjusted through secured keyboard entry. The LCD display simultaneously shows all thresholds established for both ears as well as ongoing test conditions.
