Abstract
In devising his logarithmic (log) law of sensation, Fechner assumed the subjective size of the just noticeable difference (JND) to be constant, irrespective of sensation magnitude. Fechner's assumption was later discredited when the log law failed to account for loudness data. This note reinterprets failure of the log law in terms of failure of Weber's law, and shows that Fechner's assumption is consistent with empirical studies on loudness.Keywords
