You’ll also wake up more refreshed because you spend more time in deep sleep. Plus, pink noise helps you spend more time in deep, slow wave sleepwhich improves memory recall. Studies have shown that pink noise helps reduce brain waves and increase stable sleep. Essentially pink noise is like white noise, but with a bass rumble, creating sounds like: With pink noise, the energy is more intense at lower sounds which creates a deep sound that might sound flat or even to the human ear. Pink noise is similar to white noise in that it consists of all the frequencies we hear, but the energy isn’t equally distributed across every frequency. White noise has also been shown to improve memory, tinnitus, and concentration. How does white noise help you sleep? The humming sound masks the loud sounds that disrupt your sleep, allowing you to go to sleep faster and stay asleep longer. This process creates a steady humming sound, like: White noise includes all audible frequencies, with energy equally distributed across each frequency. Noise color, or sonic hue, is determined by the energy of the sound signal and how that energy is distributed over various frequencies. So, which is better for your sleep? Let’s find out! White Noise No doubt you’ve heard of white noise, but there’s also pink, brown, and black noise, too. Or, more specifically, a type of color noise that can help your brain relax and promote better sleep!
