Does pink noise calm babies any more than white noise?

In my practise, I frequently hear of parents employing white noise gadgets or apps to calm their young children. What about Pink Noise, and does it actually work?

According to one idea, white noise may remind infants of their time in the womb, when Mum’s abdomen shielded and concealed outside noises. It’s possible that the infant will later link these noises to the womb’s natural tranquil environment.

As a newborn is born, their environment abruptly changes to one that is very exciting and boisterous, and the baby must learn to adjust.

Your infant will sleep better if white noise is used to disguise the varying levels of noise and provide the brain with a more stable acoustic environment.

Although White Noise machines are the most popular, more and more studies show that Pink Noise has long-term advantages that may make it better for babies.


A radio tuned to an unused frequency can be the source of this white noise. There is a lot of proof that white noise does help people fall asleep. It produces a consistent background noise that helps to block out other sounds, such a car door slamming outside, that could wake the baby up or prevent them from falling asleep at all!

Yet, it frequently sounds high pitched because it has equal power across all frequencies detectable to the human ear. This is due to the fact that when our ears pick up a particular sound, our brain amplifies the higher-pitched portion of the sound, making it appear louder than it actually is. However, for some people, this high-pitched sound may agitate them rather than calming them.

White noise, but the higher frequencies have been muted (think of it as white noise with the bass turned up).


Compared to white noise, it is thought to be more calming and less disturbing to sensitive hearing. Pink noise promotes deeper, longer sleep for both you and your infant when you’re dozing. Furthermore, numerous research on pink noise have also demonstrated that listening to it while you sleep might enhance both short- and long-term memory.

In one study, which was reported in the 2013 issue of Neuron, pink noise was synchronised with individuals’ brainwaves to play when their brain activity indicated deep slumber. The pink noise correlated with a longer period of deep sleep as compared to no noise.
