Magnitude of the Standard, Numerical Value of the Standard, and Stimulus Spacing in the Estimation of Loudness

Abstract

Experiments studied magnitude estimations of loudness as a function of the magnitude of the standard, the numerical value of the standard and the stimulus spacing. The results indicate that (a) the magnitude and numerical value of the standard may have marked effects on the judgment of loudnesses and (b) the distribution of the stimuli does not produce notable effects in the over-all form of the loudness function. Several possible sources of bias were investigated.
