The absolute threshold of hearing (ATH) is the minimum sound level of a pure tone that an average ear with normal hearing can hear with no other sound present. The absolute threshold relates to the ...

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.

The method of testing for the absolute threshold is similar for different sensory systems. Thus, the tester can briefly present a light or a sound (or any other kind of stimulus) at different, low intensities until the observer is unable to detect the presence of the stimulus.

The question asked in the absolute threshold method of psychophysics is, how much stimulus energy is required to elicit the response, "yes I saw something."? When dealing with color this question can take on one of two forms.

Compare absolute threshold and increment threshold paradigm ... As you can see from the above graphic, the difference between the absolute threshold paradigm and the increment threshold paradigm is the level of the background luminance. The background luminance for absolute threshold is zero.

A number of different factors can influence the absolute threshold, including the observer's motivations and expectations, and whether the person is adapted to the stimulus. Scientists have discovered that cognitive processes can influence the measurement of the threshold and that it is not as simple as once understood.
