How Pink Noise Can Help Your Baby Sleep

For many new parents, sleep may seem like a distant memory! All being well, newborns can spend up to 18 hours a day in and out of an irregular sleep schedule, punctuated by periods of wakefulness typically lasting between 1-3 hours.

In the fourth trimester, sleep for both parents and newborns can be especially erratic. Anything that can ease the process is likely to result in a more positive experience for all involved!

This is where pink noise comes in.


Pink Noise: What Is It?

Most people will have heard of white noise. Whether you’re aware of it or not, you encounter it on a pretty regular basis. However, as Meghan Neal states in a piece for The Atlantic, many of the noises we associate with white noise are in fact pink. So, what are the differences between white noise and pink noise?

White Noise

Popular Science describes white noise “a consistent noise that comes out evenly across all hearable frequencies”.

White noise is a mixture of all audible frequencies sounding with equal power, much in the same way white light is made up of all the visible colours in the spectrum.

In its purest form, white noise sounds like TV or radio static, and has the ability to mask auditory disturbances.

Pink Noise

Pink noise works in much the same way to white noise, but on a much deeper level due to its lower frequencies being more prominent and powerful.

As Neal describes, ‘“pink noise, for example, is like white noise with the bass cranked up. It’s a “shhh” sound with a low rumble mixed in, like the soft roar of a rainstorm.’

Less harsh and more balanced than its colourless counterpart, pink noise occurs in many natural rhythms, including heartbeats, making it especially comforting to newborns.

What Are the Benefits of Pink Noise Sounds for Babies?

Because pink noise is considered to be more soothing than white noise and less upsetting for baby’s sensitive ears, it can enhance slow-wave sleep by regulating brain waves, resulting in a deeper more restful night’s sleep.

Several studies have also shown that sleeping with pink noise can improve short and long term memory retention, so pink noise sounds could be helpful for the brain development of your baby.

Head in the clouds: Pink Noise Baby Sleep Aids

At Snuz, we’re known for creating ideas for happy sleep, which is why we’ve created SnuzCloud, the cutest addition to the Snuz Family.


SnuzCloud features pink noise among its 4 available sound options, which also include a soothing heartbeat, relaxing waterfall, and calming lullaby.

Having been accustomed to all kinds of noise whilst in the womb – the rush of blood, stomach gurgles and their mother’s heartbeat – SnuzCloud’s calming sounds can be just the ticket to getting your newborn to settle. With time, these sounds will become familiar to them, and your baby will associate SnuzCloud with sleep.

With easy-to-use adjustable volume, parents can ensure sound effects are just gentle enough to lull baby into a restful slumber.

The only baby sleep aid to have two light options, SnuzCloud has parents and babies covered no matter the occasion. Choose the calming pink glow that lights SnuzCloud’s fluffy cheeks to help your little one wind down.

Designed to mimic the ambience of the womb that newborns are so accustomed to, it’s an extremely comforting colour, particularly during the fourth trimester.

Incorporating this light setting as part of a bedtime routine as your baby grows will help them settle down and make the association between dimmer lights and sleep time. The second option is a soft white light. Ideal for feeding in the dark, it can also double up as a night light when little ones get older.

Naptime On the Go

If you’re looking to make the soothing pink noise sounds mobile, the SnuzCloud can easily be fastened onto a cot or crib, as well as to prams and car seats thanks to its handy Velcro strap. This flexibility makes it the ideal pink noise baby sleep aid buddy for use at home or on the go.
