Kreifeldt, J. G., Levine, S. H. and Chuang, M. C. (1988): Weber's Ratio, Multidimensional Scaling and Incomplete Data Sets: New Light on an Old Problem. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 1183-1187.

“Sensory modalities exhibit a characteristic known as Weber's ratio which remarks that when two stimuli are compared for a difference: (1) there is some minimal nonzero difference which can be differentiated and (2) this minimal difference is a nearly constant proportion of the magnitude of the stimuli. Both of these would, in a typical measurement context, appear to be system defects. We have found through simulation explorations that in fact these are apparently the characteristics required by a system designed to extract an adequate amount of information for an incomplete observation data set according to a new approach to measurement.”
