Absolute threshold

Absolute threshold refers to the minimum amount of stimulus energy required for a person to detect a particular sensation. Essentially, it is the lowest level at which a person can perceive a stimulus, such as a sound, light, or taste. For example, the absolute threshold for hearing might be the faintest sound a person can hear in a quiet environment. This concept varies among individuals and can be influenced by factors like age, health, and environmental conditions, highlighting differences in sensory perception among people.
