That’s important because deep sleep – when your body and brain waves slow down - helps you feel refreshed in the morning. Limited studies have found a positive link between pink noise and deep sleep. There is growing interest among researchers in pink noise. Many Americans fall short in both the quantity and quality categories of sleep. Adults require between seven and nine hours of sleep each night. Not getting enough can impair your ability to think clearly, concentrate and process memories. We should never underestimate the importance of good sleep. Smartphone apps offer recordings of various noise colors. If the artificial sound of rain doesn’t help you sleep, try a babbling brook or a humming air conditioner. So, what type or color of noise is most likely to help you get a good night’s sleep?

It resembles the roar of a river current, a strong waterfall or a stiff wind. It is deeper than white noises and this added depth and lower waves filter out higher sounds.īrown noise has higher energy and lower frequencies. It is considered by some researchers to be a smoother, more refined version of white noise.Įxamples of pink noise include a steady rain, wind rustling through trees, or waves on a beach. For them, there’s pink noise, which involves a consistent frequency, or pitch, to create a more even, flat sound.

So, now we can choose what type of sound best suits us at bedtime. Because we can’t count on rain to help us sleep each night, many have turned to artificial sound machines or apps designed to replicate nature’s lullabies. You don’t have to be an audio engineer to know the soothing, steady noise of a gentle shower can block out annoying sounds like barking dogs, slamming doors or honking horns that can jolt people out of all-important snooze time.
