Ernst Heinrich Weber's research in experimental psychology established the study of sensation and perception, particularly through Weber's Law. This principle explains the just-noticeable difference (JND) in stimuli, stating that the JND is a constant proportion of the original stimulus. His collaboration with Gustav Fechner advanced psychophysics, leading to the Weber-Fechner Law, which relates perceived intensity to physical intensity logarithmically. Weber's insights into sensory perception have wide-ranging implications across various fields.

Weight Perception
Weber's Law can be applied to weight perception, where a person is more likely to notice a change if it is a significant percentage of the initial weight
Auditory Perception
In auditory perception, a slight increase in volume may go undetected until it surpasses a certain percentage relative to the initial volume level

In visual perception, a minor change in the hue of a color may become noticeable only when it exceeds the just-noticeable difference
