If you are a person like me you might want to know what the colored noise is. Okay, we all heard about the white noise - this is what you hear when you match the unused radio and TV channels. Essentially, white noise is a steady flow of all or almost all auditory frequencies at the same energy level. Compared to white noise, colored noise has a lot of energy concentrated at the upper or lower limit of the spectrum, which changes the signal. For example, pink noise has a lower bass than white noise, and there is a variation in pitch and loudness, so lightning strikes like a train far away.

YouTube has lots of videos on aircraft engine noise. The reason is that it is inherently white noise. In everyday language, white noise is a steady and unchanging sound that is unobtrusive to the listener. Some insist that they are disliked by the noise of aircraft engines, but for most people, when reaching the cruising altitude, it is hardly noticeable. It becomes part of the background and makes us worry only when we have to try to talk to someone or listen to the crew's statements.

White noise is not the only noise color - the signal along the noise spectrum is called. Pink noise is concentrated at low frequencies, which is lower than white noise and has been shown to extend deep sleep. Brown noise, also called brown noise or red noise, sounds deeper than pink or white noise, and it is often compared with the low temperature of a waterfall. Brown noise is suitable for relaxation and concentration. Both scientific evidence and anecdotal evidence suggest that background noise may be good for attention and creativity, but in some cases it results in personality. Some people like complete silence and background music, some people like somewhat noisy coffee shops or fans who run in the background.
