Abstract
"The scaling of loudness by the method of magnitude estimation under a number of different stimulus spacings confirms the finding that the loudness of white noise is essentially a power function of stimulus intensity above about 40 db SPL. The over-all form and slope of the function turn out to be relatively insensitive to the spacing of the stimuli…. In contrast to the stability of magnitude estimates, category judgments of loudness vary substantially with the spacing of the stimuli. The results argue in favor of magnitude estimation over category rating in the scaling of apparent magnitude." (PsycINFO Database Record (c) 2006 APA, all rights reserved)Keywords
