Weber-Fechner equation

Japanese: ウェーバー=フェヒナーの式 - うぇーばーふぇひなーのしき
Weber-Fechner equation

…The absolute threshold is 10 −8 μW for light and 10 −10 μW/cm2 for sound intensity (which only moves the eardrum by less than 10 −9 cm). The Weber-Fechner formula and Stevens' power function proposed by Stevens SS Stevens are known as formulas that show the relationship between the magnitude of sensation and the strength of a stimulus. If the magnitude of sensation is R , the strength of the stimulus is I , and the stimulus threshold is I 0 , then R = K log I + C (Weber-Fechner formula) R = K ( I - I 0 ) n (Stevens' power function) In both cases, K and C are constants. …
