You've probably heard of white noise. Now, other colors of noise like pink and brown are increasingly popular. The continuous, ambient sounds are often used to drown out the cacophony of other noises that can keep people up at night.
The term 'color' of noise is used to describe the strength and frequency of a noise signal on the power spectrum," Shelby Harris, a clinical psychologist specializing in behavioral sleep medicine, says.
"Different colors of noise have different strengths and frequencies, and as a result, they sound different to the human ear," Harris explains. White, pink and brown noise are all types of noise with varying amounts of energy at different frequencies.
