Abstract
Fechner proposed that equally often noticed differences are subjectively equal. Parker and Schneider (1980) showed that a power-function representation for loudness was consistent with Fechner’s proposal for auditory intensity discrimination when 1-kHz tones were presented in a quiet background. In the present experiment, (1) intensity-increment thresholds were determined for 1-kHz tones in notched noise, and (2) the intensities of 1-kHz tones in quiet which produced the same loudnesses as the tones in notched noise were obtained from the same subjects. Intensityincrement thresholds in notched noise could not be accounted for by either the loudness level of the tones in notched noise or by the Parker and Schneider model. A new model is developed in which the effects of notched noise on discrimination performance are related to the effects of notched noise on loudness.
