Tinnitus sound or noise levels can lead to tinnitus. Ear plugs or other measures can help with prevention. Several medicines have ototoxic effects, and can have a cumulative effect that can increase the damage done by noise. If ototoxic medications must be administered, close attention by the physician to prescription details, such as dose and dosage interval, can reduce the damage done. If there is an underlying cause, treating it may lead to improvements. Otherwise, the primary treatment for tinnitus is talk therapy and sound therapy; there are no effective medications. The best supported treatment for tinnitus is a type of
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
