However many parents prefer the more natural sounds of pink noise. Think of it as white noise with the bass turned up!Īnother way to distinguish them is that pink noise sounds are more commonly found in nature.īoth white and pink noise help to block out external noises, which is especially useful in a busy home where you’re banging dishes or a toddler is running around. However pink noise is deeper than white noise due to a reduction in power at higher frequencies, and an increase at lower frequencies. Pink noise - which is found in Euky Bear’s Sweet Dreams Sleep Aid- is similar, in that it also contains all sounds in the range of 20-20,000 Hertz. There’s equal distribution of sound power across all the frequencies. White noise contains all sounds in the range of 20- 20,000 Hertz. So you've heard of White Noise, but what is Pink Noise? But we’re going to focus on the two which are most renowned for use in sleep – Pink and white. There’s also Pink, Brown, Purple, Blue and Gray. White noise contains all possible sound frequencies on the spectrum, just as white light contains all possible colours. People can describe the power of a noise signal using colour, in the same way you’d describe light on a spectrum. How can noise be a colour? Sonic Hues explained You’ve probably heard of White Noise machines, designed to block out external noises throughout the night – but have you heard of Pink noise? What is it? And could it be a better option for your baby? This can help us create optimal conditions for baby to drift off (and hopefully stay that way!). Thanks to sensory studies, we know a lot about sound and how it assists sleep. Baby sleep isn’t an exact science – if it were, there wouldn’t be so many tired new parents! But that doesn’t mean we can’t apply science to baby’s sleep.
