An absolute threshold can be defined as the point when the person is able to detect the presence of the stimulus. Such a point of detection is called the absolute threshold. At the volume of 2, it crossed my absolute threshold.The difference threshold can be defined as the point where a person is able to detect a difference in the stimulus, it is the amount by which a given stimulus must be increased or decreased so that one can perceive that difference. In the video, the 20 and 10 units of volume he changes to explain the concept of difference threshold to detect the differences (Brad Wray, 2013).
