What Is White Noise

Are you familiar with the term "white noise"? If not, then you should be. White noise is now very important in the fields of medicine and architecture. In today's frenzied world, white noise can be used to create tranquility even in city settings. It is very important in relieving medical conditions and improving lifestyles. It can help provide tinnitus relief, promote relaxation, induce sleep, mask sounds, and even add privacy.

White noise is a blend of all frequencies of sound playing simultaneously. It is not really a "noise," but a sound similar to a gentle hiss, to the sound of wind rustling through trees, or to the sound of a waterfall, among other pleasant things. In most cases, people who live in loud metropolitan settings use it to block out harmful noise. Because white noise features all frequencies in the correct amount, it creates a soothing sound to the human ear.

There are countless ways of taking pleasure in white noise. You can buy a pre-recorded cassette tape or a CD featuring white noise, or buy white noise generators, which are now gaining wide recognition in the market. All of these can dramatically generate a static-like swish that restrains unnecessary noises; they produce relaxing sounds similar to the flow of a stream. This sound is very ideal if you want to unwind.

White noise is also applicable in the field of architecture acoustics. In fact, some sirens for emergency motor vehicles use white noise because of its capacity to curtail unwanted background noise, especially the traffic noise in the city. It is also helpful in the field of electronic music, where it is used to produce other kinds of sounds in various frequencies.

White noise is also used to either calm or disorient people before they undergo cross-examination or investigation. In some cases, white noise is used as part of sensory deprivation procedures.
