There are times when the space around you is just too loud and you need some kind of a white noise to mask all those distracting sounds, which may come from your noisy neighbors while you are trying to sleep, or from loud colleagues when you are trying to focus on your job, or from a TV in the next room while you are trying to study.

White noise is a noise in which all sound frequencies audible to human ear are in equal intensity (desibels). Due to the fact that human ear is made in a such way that it is more sensitive to sound frequencies between 2-5kHz white noise does not sound very pleasant to most of the people if played loudly.
Therefore many listeners prefer pink noise or brown noise. These noises have more powerful bass frequencies and less powerful higher frequencies (brown noise has even more powerful bass than pink).

Sometimes people by words \\"white noise\\" mean any kind of noise which can mask other unwanted sounds. The role of such "white noise" may play a sound of a hair dryer, sound of rain, sound of waterfall etc.

In one sentence, noises such as pink noise covers unwanted noises so it helps us to sleep well or concentrate on something.
