What is white noise?
Simply put, white noise is a sound signal which is used to mask background sounds. White noise is great when used as a sleep aid, study aid, for focus, or to soothe a baby, because it will drown out sounds which may be distracting.
Technically speaking, white noise is a sound that has a constant volume throughout the entire audible frequency range. It is all of the frequencies combined together, similar to how white light is all of the colour frequencies combined together.
Why use white noise?
Our hearing works a little like an alarm system, although we may be relaxed, any loud sounds can wake us up, or break our focus. Because white noise drowns out other sounds frequencies, our hearing is less likely to bring us to an alert state if there is a loud sound outside our room, like a dog barking or car horn honking.
What is noise masking?
When you add white noise to your room, you are using a principal called noise masking. Imagine a distracting sound is like a candle burning in a dark room, the light from the candle would seem very bright, however, turn on the bright overhead light and the candle would no longer seem bright. In this example white noise is the bright overhead light.

How did we create our white noise on Youtube?
Aaron J. Cunningham, our resident music dude, was set to the task of creating the white noise. He did so by combining multiple white noise generators from analog synths such as the Arp Odyssey, SH-101, Dave Smith Evolver, and Yamaha CS-80.
