Basically, white noise and pink noise are two types of generate acoustic sound. For the reason that they both used to cover disturbing sound in a pleasing way, a lot of people are still bewildered and find it hard to distinguish the differences between white noise and pink noise. For many people, white noise sounds like a running water or rain. It is even similar to the noise of a vacant TV channel. On the other hand, pink noise is described as similar to the sound of calibrated audio equipment. White and pink noise, in some cases, is merged with other sound to generate amusing masking programs such as thunder, fountains, and fan noise.

Now, white noise is a signal whose spectrum is a horizontal line - there is equal amount of energy at every frequency. This is the reason why it is projected to be comparable to white light. Given that white light involves all light frequencies, white noise contains all sound frequencies. Usually, it is done by creating random frequencies in equal proportions per octave either with the use of computer, dedicated synthesizer or a special electronics. It successfully increases the high frequency content due to the factor that every increasing octave is double size of the previous. It is called white because there is nothing distinctive about any part of it just like a white-painted wall.

If white noise is equal the amount of energy per frequency, pink noise is the amount of energy per octave. Pink noise is basically white noise. The thin line that separates pink noise from white nose is that it has decreasing amplitude and increasing frequency at a constant rate per octave. Most simply put, the low frequencies are highlighted as an outcome. White noise has the same level at all the frequencies it is played, but pink noise has more red components, which are considered lower frequencies. It is called pink, because of the position it holds between red and white.

In audio, pink noise is the most frequent color encountered. From one octave to the next we expect to hear a suitable amount of sound energy (depending upon the program material), which is why we standardize our audio systems to pink noise. White noise also sounds like the hiss of an untuned FM radio or the background noise on a cassette tape. The sound of the high noise is taken over by the very highest frequencies which are due to the particular characteristics of human ear. On the other hand, pink noise is described as similar to the sound of a hiss mixed with a rumble or like the noise inside a airline passenger seat.

Normally, the sound generated by electronic masking systems is mislabeled as white noise. Though masking noise is closer to pink noise than white noise, white noise has already become the generic term for masking noise. If you want to learn more about these types of noise, and their relation to human sleep patterns, you can check out sites that offer products that make such noises. Today, these are popular alternatives for helping people with sleep problems.
