What is White noise?
White noise is the random nondescript static sound produced by various electronic devices. The sound covers and combines all wavelengths and frequencies. In this way it is like the colour white which is really a combination of all colours. Hence the name white noise – the combination of all sounds. Examples of common white noise sources are the radio or television static when set to an empty channel, the hum of an electric fan motor and the babbling sound of a fast movie stream.
Over the years white noise has been used for many different situations such as in the aid to train soldiers, to torture and in more recent times to help with sleep, relaxation, to calm infants and Tinnitus.
White noise has a variety of benefits and applications. Because of its sound masking properties, white noise is ideal both as a concentration aid and a relaxation aid. It is useful in a huge range of situations.
It is thought that if a person hears white noise and only they can hear it they could possibly be having a spiritual awakening. So if white noise is given to a person does this automatically mean that this could be opening a persons ‘third eye’? A lot of people will buy mediation C.D’s or download pure white noise to mediate too and most claim it to work.
Paranormal Research – The White Noise Theory
The white noise theory is widely used in the investigation of EVPs (Electronic Voice Phenomena). It often used a huge debate between researchers with some believing
There are two theories on the use of white noise for EVP investigations:
Using white noise during EVP investigations relies on the random sound reorganization theory of EVP formation. That theory holds that entities take sounds in the ambient environment and somehow reorganize them into coherent words for us to hear. By providing a white noise source (or at least investigating near a white noise source) you are providing a base of raw sound (“raw material”) for the entity to use to form communication. However, a significant drawback to use this technique the white noise can be hard to filter out later when you analyse your recordings and can then contaminate an otherwise good EVP recording.
This theory is that white noise can be used to filter out background noise or enhance EVPs when listening to recordings.
- To use white noise in this way place the EVP recorder player (or speaker) on one side of you and the white noise source on the other sides. Stand (or sit) in the middle and turn both on.
As you listen to the recording the white noise source will either filter out background noise on the recording and/or enhance any EVPs captured.
There is some evidence this could work. Noise cancelling headphones is based on a similar principle. These types of headphones play low levels of white noise through the speakers to filter out surrounding noise and enhance the quality of the audio.
