It can be concluded that both data points whose intensities are equal to the absolute threshold and the just noticeable intensity must belong to the curve of Equation (2).
Afterward, either absolute threshold or just noticeable intensity is expectedly obtained from the general logarithmic nature function, which facilitates the determination of optimal QoE threshold.
Absolute threshold shifts (1, 2, 3, and 4[degrees]C) and relative threshold shifts (25, 50, 75, and 100%) were each combined with reductions in the slope of the ERF (5, 10, 15, 20, and 25%).
The ranges are 49% (absolute threshold shift), 94% (relative threshold shift), 28% (reduction in slope of the ERF), 68% (absolute threshold shift combined with a reduction in slope of the ERF), 103% (relative threshold shift combined with a reduction in slope of the ERF), and 76% (analog ERF).
On their face, nothing distinguishes relative threshold labels from absolute threshold labels.
Labels that present aggregated information in terms of a threshold may employ absolute thresholds of nutritional value or relative thresholds that compare a product to other products within a food group.
Quantitative predictions about masked CDTs need the (squared) absolute threshold
as an index of power of internal noise (i.e., as a limit of the observer performance in the absence of external noise).
However, in practice absolute thresholds
usually cannot withstand the pressures of changing circumstances and are not as absolute as the term would appear to imply.

were set at various intensity values, including 90[degrees], 95[degrees], 100[degrees], and 105[degrees]F.
It should be emphasized that the data in the present study pertain to the absolute thresholds
of train horn sounds, operationally defined as the level at which a listener can detect the signals 50% of the time.
