The answer is an absolute threshold.

Explanation:

An absolute threshold usually refers to the lowest level of a stimulus that can be detected by an organism. These stimuli can be light, sound, touch, among others.

The signal detection theory has had some kind of influence in the absolute threshold because in this way a specific stimulus can be detected concerning a specified percentage. This percentage is usually 50%. Some factors can influence the absolute threshold. They include the subject's motivations and expectations, cognitive processes, as well as how the subject is related to the stimulus.
