The absolute threshold for sound is the minimum amount of sensation needed to elicit a response from receptors in the ears.
12.
In contrast, human senses are highly nonlinear-for instance, the brain totally ignores incoming light unless it exceeds a certain absolute threshold number of photons.
13.
Exactly what evidence is sufficient to prove something is also strongly area-dependent, usually with no absolute threshold of sufficiency at which evidence becomes proof.
14.
By measuring this minimum intensity for testing tones of various frequencies, a frequency dependent absolute threshold of hearing ( ATH ) curve may be derived.
15.
Measuring poverty by an absolute threshold has the advantage of applying the same standard across different locations and time periods : it makes comparisons easier.
16.
In 1962, Eugene Galanter, a psychologist, tested stimuli till people were able to feel them approximately 50 % of the time, then used the following as examples of absolute threshold:
17.
In addition to thresholds that are designed to operate " quickly ", islanding detection systems also have absolute thresholds that will trip long before conditions are reached that could cause end-user equipment damage.
18.
At the low end of the range is the absolute threshold of vision for a steady light across a wide field of view, about 10 " 6 cd / m2 ( 0.000001 candela per square meter ).
19.
A threshold ( or limen ) is the point of intensity at which the participant can just detect the presence of a stimulus ( absolute threshold ) or the presence of a difference between two stimuli ( difference threshold ).
20.
Unlike noise-shaping algorithms based on an Absolute threshold of hearing model ( i . e . the quietest sound that can be heard on otherwise silent conditions ), POW-R has been designed to give optimal performance at normal listening levels.
