The masking threshold is calculated using the absolute threshold of hearing and the principles of simultaneous masking — the phenomenon wherein a signal is masked by another signal separated by frequency, and, in some cases, temporal masking — where a signal is masked by another signal separated by time.

A similar phenomenon is paranoia in the elderly when poor eyesight, hearing and memory causes the person to be abnormally suspicious of the environment.

Dream incorporation is a phenomenon whereby an actual sensation, such as environmental sounds, is incorporated into dreams, such as hearing a phone ringing in a dream while it is ringing in reality or dreaming of urination while wetting the bed.

Beliefs associated with this phenomenon include divine healing, receiving visions, being set free of demonic spirits, hearing God speak.

A similar coupling phenomenon was characterized in hearing aids when the adaptive feedback cancellation is used.

It may also describe a similar phenomenon that occurs when one may immediately detect words of importance originating from unattended stimuli, for instance hearing one's name in another conversation.

One of the finest natural examples of this ordering phenomenon can be found in precious opal, in which brilliant regions of pure spectral color result from close-packed domains of amorphous colloidal spheres of silicon dioxide ( or silica, SiO < sub > 2 </ sub >).

Although quarks also carry color charge, hadrons must have zero total color charge because of a phenomenon called color confinement.

Previously, other researchers had observed distinct color effects when cooling cholesterol derivatives just above the freezing point, but had not associated it with a new phenomenon.

Due to a phenomenon known as color confinement, quarks are never directly observed or found in isolation ; they can be found only within baryons or mesons.

Other than this nomenclature, the quantum parameter " color " is completely unrelated to the everyday, familiar phenomenon of color.

Rayleigh scattering is a spectroscopic scattering phenomenon that accounts for the color of the sky.

In QCD this phenomenon is called color confinement ; it implies that only hadrons, not individual free quarks, can be observed.

The term opalescence is commonly and erroneously used to describe this unique and beautiful phenomenon, which is correctly termed play of color.

This phenomenon is called a red tide, from the color the bloom imparts to the water.

Iris color is a highly complex phenomenon consisting of the combined effects of texture, pigmentation, fibrous tissue and blood vessels within the iris stroma, which together make up an individual's epigenetic constitution in this context.

Color confinement, often simply called confinement, is the physics phenomenon that color charged particles ( such as quarks ) cannot be isolated singularly, and therefore cannot be directly observed.

In the early 1970s, Land attempted to explain the previously known phenomenon of color constancy with his Retinex theory.

Contrasting the film's vintage black-and-white film footage, these persons appear in color segments as themselves, commenting in the present day on the Zelig phenomenon as if it really happened.

A transient lunar phenomenon ( TLP ), or lunar transient phenomenon ( LTP ), is a short-lived light, color, or change in appearance on the lunar surface.

The refractive index of many materials ( such as glass ) varies with the wavelength or color of the light used, a phenomenon known as dispersion.

Because of a phenomenon known as color confinement, a hadron cannot have a net color charge ; that is, the total color charge of a particle has to be zero (" white ").

This is the same phenomenon that gives neon signs their characteristic color.

Simultaneous contrast is a psychophysical phenomenon of the change in the appearance of a color ( or an achromatic stimulus ) caused by the presence of a surrounding average color ( or luminance ).

The phenomenon in helium-3 is thought to be related to pairing of helium-3 fermions to make bosons, in analogy to Cooper pairs of electrons producing superconductivity .< ref >

The physical basis for this phenomenon also comes from the pairing effect in nuclear binding energy, but this time from both proton-proton and neutron-neutron pairing.

Some anticodons can pair with more than one codon due to a phenomenon known as wobble base pairing.

The extremity of this phenomenon can be found in many fan fiction archives, where fanfiction is searchable by rating, length, genre, date, language, and " pairing ".

They represent two abstract and complementary aspects that every phenomenon in the universe can be divided into.

The puzzling phenomenon of two individuals being exposed to the same evidence and being able to reach different conclusions, has been frequently explained ( particularly by Daniel Kahneman ) by reference to a ' bounded rationality ' - that is most judgments are made by fast acting heuristics ( system 1 ) that work well in every day situations, but are not amenable to decision making about complex subjects such as climate change.

The phenomenon was further investigated by Ampère, who discovered that two parallel current-carrying wires exerted a force upon each other: two wires conducting currents in the same direction are attracted to each other, while wires containing currents in opposite directions are forced apart.

Isomorphisms are studied in mathematics in order to extend insights from one phenomenon to others: if two objects are isomorphic, then any property that is preserved by an isomorphism and that is true of one of the objects, is also true of the other.

In physics, interference is a phenomenon in which two waves superimpose to form a resultant wave of greater or lower amplitude.

However, longitudinal waves by necessity have only one form for a given propagation direction, rather than two polarizations as in a transverse wave, and thus they were unable to explain the phenomenon of birefringence, where two polarizations of light are refracted differently by a crystal.

There are two main perspectives on the origins and basis of nationalism, one is the primordialist perspective that describes nationalism as a reflection of the ancient and perceived evolutionary tendency of humans to organize into distinct grouping based on an affinity of birth ; the other is the modernist perspective that describes nationalism as a recent phenomenon that requires the structural conditions of modern society.

There are two major bodies of thought on the causes of nationalism, one is the modernist perspective that describes nationalism as a recent phenomenon that requires the structural conditions of modern society, in order to exist ; the other is the primordialist perspective that describes nationalism as a reflection of the ancient and perceived evolutionary tendency of humans to organize into distinct grouping based on an affinity of birth.

A more plausible theory to explain motion perception ( at least on a descriptive level ) are two distinct perceptual illusions: phi phenomenon and beta movement.

At the time the two of us were in Heliopolis and we both witnessed the extraordinary phenomenon of the moon hiding the sun at the time that was out of season for their coming together ... We saw the moon begin to hide the sun from the east, travel across to the other side of the sun, and return on its path so that the hiding and the restoration of the light did not take place in the same direction but rather in diametrically opposite directions ..."

Signal processing can take advantage of this phenomenon to reduce the noise floor using two strategies.

* The Harry Ransom Center at the University of Texas at Austin holds over 1, 500 items related to the Rubaiyat, including two copies of the first edition, hundreds of editions, translations, and parodies, several Persian manuscripts containing rubaiyat, and ephemera, manuscripts and correspondence documenting the phenomenon of " Omariana "

These two sectors are not independent: the abundance of natural resources and the development of the oil and gas sector might be the most important cause for the underdevelopment of other sectors, a phenomenon called ‘ Dutch Disease ’.

* Werner Israel, physicist who discovered the important phenomenon of mass inflation, and together with Stephen Hawking, coeditor of two important celebratory volumes

This phenomenon can occur because the medium is moving in the opposite direction to the wave, or it can arise in a stationary medium as a result of interference between two waves traveling in opposite directions.
