Just the point at which where you can hear it: differential threshold. Is the ability in the sensory system to detect changes in a stimulus or difference between stimuli. Sensory system to tell the difference between two different stimuli: there is a noticeable difference. Just noticeable difference: the min changes in a stimulus that difference can be detected, volume example, differential threshold: turning up volume to a point where you can tell the difference between the two volumes (initial and new) Just noticeable difference: volume 3 is your absolute threshold, you then notice a difference at 6. Jnd would be the amount that had to change to get there: weber"s law, as intensity of initial stimulus increases, people"s ability to discriminate between the initial and the new one decreases, ratio.
