Grey noise

Grey noise is a type of sound that is a mix of different frequencies. It is called "grey" because it is in between white noise and black noise. White noise is like when you listen to a TV that is not tuned to a channel, and black noise is like when there is complete silence.

Grey noise is a type of sound that is used to eliminate distractions while you are trying to concentrate or sleep. It is also used in testing equipment to make sure it is working properly.

You can think of it like a big bowl of different colored marbles. White noise would be like a bowl filled with all white marbles, black noise would be like a bowl filled with all black marbles, and grey noise would be like a bowl filled with both white and black marbles mixed together.

Overall, grey noise is a type of sound that is meant to be calming and help you focus. It is great for taking a nap or studying.
