Stochastic comparisons of distorted variability measures
In this paper, we consider the dispersive order and the excess wealth order to compare the variability of distorted distributions. We know from Sordo (2009a) that the excess wealth order can be characterized in terms of a class of variability measures associated to the tail conditional distribution which includes, as a particular measure, the tail variance. Given that the tail conditional distr...
متن کاملLoudness and Loudness Discrimination Revisited
We present evidence that the psychophysical function relating loudness to sound pressure is governed by a nonlinear gain control system, one of whose functions is to protect the sensory system from overload. Specifically, the loudness function is altered nonlinearly when loud sounds are added in an identification task previously containing only soft sounds but not vice
متن کاملTemporal integration of loudness, loudness discrimination, and the form of the loudness function.
Temporal integration for loudness of 5-kHz tones was measured as a function of level between 2 and 60 dB SL. Absolute thresholds and levels required to produce equal loudness were measured for 2-, 10-, 50-, and 250-ms tones using adaptive, two-interval, two-alternative forced-choice procedures. The procedure for loudness balances was new and employed ten interleaved tracks to obtain concurrent ...
متن کاملDisturbances of loudness perception.
This article reviews information on some auditory disorders that have in common a disturbance in loudness perception. The perceptual disturbances in these disorders have interchangeably been labeled "hyperacusis," "dysacusis," or "phonophobia." Our question concerns whether the loudness disturbances associated with these auditory disorders are sufficiently different as not to justify the equiva...
متن کاملVariability and sequential effects in cross-modality matching of area and loudness.
Individual subjects' performance was examined for cross-modality matching (CMM) of loudness to visual area, as well as for magnitude estimation (ME) of the component continua. Average exponents of power functions relating response magnitude to stimulus intensity were .73 for area, .20 for loudness, and 2.44 for CMM. Predictions of the CMM exponent based on ME were higher than the empirical valu...
