Abstract
The preliminary theory of intensity resolution [N. I. Durlach and L. D. Braida, J. Acoust. Soc. Am. 46, 372–383 (1969)] is extended to encompass mean loudness matches between different types of stimuli. According to this extension, two stimuli S1 and S2 are matched in loudness when their intensities I1 and I2 divide the dynamic ranges proportionately in terms of number of JND's. This theoretical relation between loudness matching and resolution (originally proposed by Riesz) is compared to experimental data on equal‐loudness contours for tones, loudness matching of a tone in silence versus the same tone in noise, and loudness matching of a tone presented to a normal ear versus the same tone presented to a recruiting ear.
