How is pink noise generated?
The principal sources of pink noise in electronic devices are almost invariably the slow fluctuations of properties of the condensed-matter materials of the devices. In many cases the specific sources of the fluctuations are known.
What is pink noise used for?
Pink noise is often used as a background or control noise because research has found that it is less distracting than other types of noise. For example, one study found that participants became less stressed after listening to pink noise, compared with the typical sounds of an intensive care unit.
