Graphic recordings were obtained of the absolute thresholds to a series of twenty (20) pure tones, in equal-mel steps from 200 to 6000 cps, in steps of 1 db. Each tone was pulsed on a 0.50 duty cycle with a 500-msec duration for a period of 30 sec. The equipment was carefully calibrated to yield thresholds in db SPL. Fifty-seven young male adults with normal (plus or minus 15-db) hearing served as the observers. The data were normalized, a product-moment correlation applied, and the correlation matrix factored according to the complete centroid technique. Three significant oblique factors were obtained. The first had high loadings in the 200 to 1000-cps range, the second loaded high from 2200–6000 cps, and the third yielded high loadings in the 1200 to 2000-cps interval. Results are discussed in relation to Wever's theory of audibility.
