Tinnitus masker Tinnitus masker Tinnitus maskers are a range of devices based on simple white noise machines which are used to add natural or artificial sound into a tinnitus sufferer's environment in order to mask or cover up the ringing. The noise is supplied by a sound generator which may reside in or above the ear or be placed on a table or elsewhere in the environment. The noise is usually white noise or music, but in some cases it may be patterned sound or specially tailored sound based on the characteristics of the person's tinnitus. The perceived loudness of tinnitus, called
Black-body radiation logically determined solely by its own internal state. The causal effect of thermodynamic absorption on thermodynamic (spontaneous) emission is not direct, but is only indirect as it affects the internal state of the body. This means that at thermodynamic equilibrium the amount of every wavelength in every direction of thermal radiation emitted by a body at temperature "T", black or not, is equal to the corresponding amount that the body absorbs because it is surrounded by light at temperature "T". When the body is black, the absorption is obvious: the amount of light absorbed is all the light that hits
