Noise machines are not just for babies anymore. More and more people are turning towards noise machines to promote relaxation and sleep, and there is a new trend that’s called “pink noise”. Pink noise machines are claimed to be soothing and calming and they are associated with many benefits such as improved memory and focus. Pink noise as well as white noise, both contain frequencies that all humans can hear and that range between 20 hertz to 20,000 hertz. While white noise has “equal power across all frequencies”, pink noise “is more powerful on the lower end of the sound spectrum”. To simplify things, white noise is just like the static you hear on old TV sets, while pink noise is steady just like the sound of rusting leaves or falling rain. Before you go ahead and invest in a noise machine, test the sounds out by listening to tracks on YouTube or Spotify. We list for you below some of the known benefits of pink noise as well as some of the best noise machines online.
1 || Helps Cure Insomnia
Since pink noise provides a consistent source of ambient sound, it not only lulls anyone to sleep, it also helps mask all the city sounds. So the chances of you being jolted awake by a street sound or the sounds of your house are almost next to nil.
2 || Slows Down Our Brain Waves
Deep sleep or slow-wave sleep is the only type of sleep that allows you to wake up feeling refreshed and energised. I’m sure you’re familiar with it as I’m also sure that we don’t get to experience that very often. Slow-wave sleep is needed for our bodies to work on repairing and fixing itself such as repairing muscles, regrowing tissues, and improving our immunity. Pink noise will promote continuous sleep so that you can easily reach that stage of sleep, and according to sleep coaches, it is believed that the frequencies of our brain waves adjust to pink noise thus promoting further rest.
3 || Improves Memory
The memory improves drastically when you are able to go into deep sleep with the aid of pink noise. When we are adequately rested, the memories we made during our waking hours will become relocated from the ‘hippocampus’ to the ‘cortex’ where long-term memories are saved. The research done on this correlation is small, yet it is believed that memory processing is greatly improved due to the effect pink noise.
4 || Enhances Focus
Pink noise’s ability to mask sounds is also great associated with increased focus. External sounds that penetrate our subconscious brain while we sleep, greatly interfere with our ability to focus. The constant soothing sounds of pink noise are also very helpful when you’re trying to work in a café, open office or at your house.
