Gee, google only returned about 6,000 websites, I would assume whatever you are looking for would be answered in one of those first few pages.skinnyl said:yeah tried google, this is for my acoustics exam in a few days, so biology might not be the best place :s. The stimuli also includes sound.

The Weber-Fechner Law is a psychophysics principle that describes the relationship between the physical intensity of a stimulus and the psychological perception of that stimulus.
The Weber-Fechner Law was developed by two German scientists, Ernst Heinrich Weber and Gustav Theodor Fechner, in the mid-19th century.
The formula for the Weber-Fechner Law is S = k log R, where S represents the perceived sensation, k is a constant, and R is the physical stimulus intensity.
The variables in the Weber-Fechner Law formula are S (perceived sensation), k (constant), and R (physical stimulus intensity).
The Weber-Fechner Law explains human perception by stating that the perceived sensation of a stimulus is not directly proportional to the physical intensity of the stimulus, but rather increases logarithmically as the physical intensity increases. This means that small changes in physical intensity can result in larger changes in perceived sensation, and vice versa.
