Definition (alternative):
A term often used in neuroscience and experimental research. An absolute threshold is the smallest detectable level of a stimulus. 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.*

Contextual explanation:
Absolute threshold is the very minimum stimulation needed for a person to detect that particular stimulus 50 percent of the time. Each people has different absolute threshold; to test one's absolute threshold -for example, for hearing-hearing specialist will expose the patient to various sound levels. The absolute threshold will be the pitch which the patient can hear half of the tim; "the 50-50 point defines yourabsolute threshold"(Myers 195).
Other senses such as seeing, feeling, tasting, or smelling, can also be tested by similar methods.
