WHITE NOISE Meaning and
Definition
-
White noise refers to a type of random signal that contains an equal amount of energy across all frequencies. The term "white" refers to the equal distribution of energy, much like how white light contains all colors of the visible spectrum. It is a form of noise that encompasses a wide range of different frequencies, typically spanning the entire audible spectrum.
White noise is often experienced as a steady, constant hissing or buzzing sound, similar to the sound of a television or radio station in between channels. It is created by combining sounds of all different frequencies together, in equal proportions, resulting in a continuous and constant stream of noise. This sound is often used as a "masking" technique to drown out other sounds and create a constant and unobtrusive background noise.
White noise has a variety of applications in different fields. It is commonly used in audio engineering, where it can be used to test and calibrate audio equipment, as well as mask unwanted background noise during recordings. It is also used in the field of psychoacoustics, where it is employed in experiments to study the perception of sound. Additionally, white noise is utilized in various therapeutic techniques, such as in sleep aids, relaxation techniques, and sound therapy, due to its ability to block out other sounds and induce a state of relaxation or focus.

Etymology of WHITE NOISE
The term "white noise" originated from the concept of white light. In the field of optics, white light is a combination of all visible colors, each with a different frequency. Similarly, white noise is a sound that contains all audible frequencies combined in equal intensity. The term "white" refers to the color white, which symbolizes this mixture of frequencies in both light and sound. The word "noise" here is used in the general sense of any unwanted or random sound. Consequently, "white noise" signifies a type of sound that encompasses all audible frequencies at equal intensity, resembling the concept of white light.
