DETECTION THRESHOLDS AND PURE TONE THRESHOLDS IN AUDITORY ACUITY
Abstract
Research was conducted to determine whether subjects could set up and maintain some criterion of minimum tonal quality and if so, whether such a threshold could be even more precise than the threshold of detection. A more precise threshold, in the sense of a steeper psychophysical function, would be of some use in determining the loudness level of pure tones, in defining signal- to-noise differentials in psychological terms, and the like. The data indicate that a zone of detectability of the order of 2-3 decibels exists between the intensity at which a tone is just detected 50% of the time and the intensity at which it may be assigned a pitch quality 50% of the time.
