Answer;

-Absolute threshold

Absolute threshold is the minimum intensity of a physical stimulus that can just be detected by an observer.

Explanation;

An absolute threshold is the smallest level of stimulus that can be detected, usually defined as at least half the time.

-It can be applied to any stimulus that can be detected by the human senses including sound, touch, taste, sight, and smell. For example, in an experiment on sound detention, researchers may present a sound with varying levels of volume. The smallest level that a participant is able to hear is the absolute threshold.
