White noise is a type of noise that is produced by combining sounds of all different frequencies together. If you took all of the imaginable tones that a human ear can hear and combined them together, you would have white noise.
The adjective “white” is used to describe this type of noise because of the way white light works. White light is light that is made up of all of the different colors (frequencies) of light combined together (a prism or a rainbow separates white light back into its component colors). In the same way, white noise is a combination of all of the different frequencies of sound.
Sound exists on all frequencies and voices through white noise are said to vibrate at high frequency as realities consist of multidimensional grids created by sound, light, and colour. If you tune into a frequency signature, station, channel and you can hear whatever is on that station. Some believe that there are particular frequencies that are more attuned to pick up spirit voices.
