The Weber-Fechner law. (English) Zbl 1241.91104

Summary: We shall elucidate the reason why the degree of disturbance by noise is measured in logarithmic scale by the Weber-Fechner law in psychometrica. This in turn relies on the solution to the Schröder equation in the theory of functional equations. We shall solve it by the method of [M. Kuczma, Functional equations in a single variable. Warszawa: PWN – Polish Scientific Publishers (1968; Zbl 0196.16403)].
