WebFechner's law states that the subjective sensation is proportional to the logarithm of the stimulus intensity. According to this law, human perceptions of sight and sound work as follows: Perceived loudness/brightness is proportional to logarithm of the actual intensity measured with an accurate nonhuman instrument. [7] WebApr 24, 2024 · If the first time you can detect sound is at a volume setting of 4, this is your absolute threshold. As you continue to increase the volume, what you are doing is increasing the intensity of the stimulus. The Weber-Fechner Law began as a simple equation developed by Weber that Fechner expanded on.

WebThe absolute threshold is one type of sensory threshold [to glossary]. A threshold is a type of sensory limit which draws on the analogy of the threshold to a room.
