Black noiseīlack noise is an informal term used to describe lack of noise. But according to anecdotal evidence, the deepness of brown noise can induce sleep and relaxation. There isn’t enough hard research to support the effectiveness of brown noise for sleep. Though brown noise is deeper than white noise, they sound similar to the human ear. This makes it deeper than pink and white noise. Brown noiseīrown noise, also called red noise, has higher energy at lower frequencies. That’s why it’s often recommended for sleeping difficulties and sleep disorders like insomnia. Since white noise contains all frequencies at equal intensity, it can mask loud sounds that stimulate your brain. The equal distribution creates a steady humming sound. Energy is equally distributed across these frequencies, unlike the energy in pink noise. White noise includes all audible frequencies. However, compared to brown noise, pink noise isn’t as deep. It’s like white noise with a bass rumble. There are many color noises, including: Pink noise These color noises, or sonic hues, depend on the intensity and distribution of energy. How does pink noise compare to other color noises? More research is needed to understand how pink noise can improve quality and duration of sleep. There’s more evidence on the benefits of white noise for sleep. There isn’t a lot of scientific research on pink noise, though. Deep sleep supports memory and helps you feel refreshed in the morning. In a small 2012 study in the Journal of Theoretical Biology, researchers found that steady pink noise reduces brain waves, which increases stable sleep.Ī 2017 study in Frontiers in Human Neuroscience also found a positive link between pink noise and deep sleep. You can listen to them on a computer, smartphone, or sleep machine like a white noise machine. These sleep-inducing sounds are known as noise sleep aids. Other sounds can relax your brain and promote better sleep. Some noises, like honking cars and barking dogs, can stimulate your brain and disrupt sleep. Since your brain continues to process sounds as you sleep, different noises can affect how well you rest. Can pink noise help you get a better night’s sleep?
