In pink noise, each octave interval (halving or doubling in frequency) carries an equal amount of noise energy.. According to the Centers for Disease Control and Prevention (CDC), 30 percent of American adults don’t get enough sleep each night. Brown noise is one of the many colors of noise, which also include white noise, pink noise and blue noise. However, brown noise doesn't get its moniker from the color — it's actually named after botanist Robert Brown, who discovered Brownian motion (random particle motion) in the 1800s. Since white noise contains all frequencies at equal intensity, it can mask loud sounds that stimulate your brain. Every octave of pink noise contains an equal amount of energy and therefore it is popularly used in sound engineering techniques. I love it!
