Anything you can hear, touch, smell, taste, or see has a difference threshold when something is added or taken away from it long enough to notice a difference. In psychophysics, the smallest detectable change in a stimulus or difference between two stimuli that can be reliably detected, often defined as the difference for which the percentage of correct discriminations is 75 per cent, though other percentages are sometimes used.
