Microprocessor versus self-recording audiometry in industry.
Auditory thresholds of 46 industrial workers tested on both a self-recording audiometer and a microprocessor audiometer showed significant differences at 2, 3, 6, and 8 kc/s with the self-recording instrument measuring lower thresholds by from 2.3 to 6.7 db. Differences appear to be the result of the psychophysical methods used and the use of pulsing versus steady tones. The differences, though significant, should be of little consequence in a carefully administered industrial hearing conservation program.
