▷ White Noise FAQ

White noise is a sound created by combining sounds of different frequencies. If you combine all the sounds that a person can hear, you get white noise.

The reason we use the adjective “white” to describe this kind of noise is because that is how white light works. White light is light made up of all the colors (frequencies) of light (prisms and rainbows break down white light into its respective colors). In the same way, white noise is a combination of all the different frequencies of sound. White noise can be thought of as 20,000 sounds being played simultaneously.

Excessive white noise above the allowable decibel level can be harmful to babies’ ears, causing more damage than if they were not exposed to the noise at all. It is important that the volume of white noise is not too loud for either babies or adults. The noise level should be kept to about 65 dB, which is about the level of a gentle shower.

There was some evidence that continuous noise shortens the time it takes to fall asleep, but the quality of the evidence was very poor, and at least one study suggested that noise could cause more sleep disturbances.

Depending on how you use it and where you are, white noise is said to focus the auditory center of the brain and improve concentration and memory. However, since the brain tends to adapt to what it hears, white noise is not good for brain function in the long run.

However, softer, repetitive sounds have great potential to relax the nervous system. White noise, such as the sound of television, rain, and waves, is a stable acoustic environment that many people use to improve their sleep quality, relieve anxiety and tension, and uplift their mood.

It has been scientifically proven that silence has a positive effect on people and their sleep. But if you can use noise masking, white noise, pink noise, etc. to help you sleep more easily or better, that’s simply wonderful. Noise masking, white noise, etc. are very clear.

White noise is a very effective sound source for promoting a deep and relaxed state of consciousness, and can have a variety of therapeutic effects, including promoting deep sleep and treating insomnia. It can be used (especially in combination with binaural beats) to deepen meditation.

The most probable causes are musical ear syndrome, apophenia, and audio pareidolia. The brain tries to understand sounds by recognizing patterns. Sometimes, it misinterprets what it hears. For example, in pareidolia, it interprets meaningless sounds as something it has heard before, such as music.

White noise is used in many relaxation therapies because, scientifically speaking, noise has a calming effect by masking other sounds. When you listen to white noise, your ears and cerebral cortex become saturated, and other sounds cannot cross this auditory barrier.
