Why White Noise Calms Babies: Unraveling the Mystery

May 17, 2024

Being a new parent can be quite challenging, especially when it comes to calming a fussy baby. You've tried rocking, cuddling, and feeding them, but nothing seems to work. And then, you come across the idea of using white noise as a means to soothe your baby and wonder, why does white noise calm babies?


White noise, as it turns out, has a fascinating reason for its efficacy in calming babies. In this article, we'll explore what white noise is and why it's so helpful in helping your little one relax.


What is White Noise?


White noise is a type of noise that contains an equal amount of sound frequencies, making it sound like a constant hum or buzz. It effectively masks other sounds by creating a uniform blanket of noise, making it harder to discern individual sounds within its frequency range.


Why Does White Noise Calm Babies?



  1. Familiar Environment: Before birth, babies are accustomed to hearing constant, low-level noise in the womb. We can compare the sound of amniotic fluid rushing around them to white noise. As a result, when they're born, white noise provides a sense of comforting familiarity, similar to what they experienced in utero.



  2. Masking Distractions: Babies, especially newborns, are sensitive to sudden sounds and changes in their environment. White noise helps to create a consistent auditory backdrop that can mask sudden or abrupt noises that might otherwise startle or disturb them in their sleep or during moments of relaxation.



  3. Sleep Aid: Sleep is a vital part of early development for babies. White noise helps to create a sleepy atmosphere, encouraging restful sleep. The monotonous sound, devoid of any discernible patterns, helps prevent their minds from becoming too active and overstimulated during bedtime.





  1. Calms the Fight or Flight Response: When confronted with sudden, loud noises, one's fight or flight response is often triggered. This can be quite overwhelming for a newborn or young baby. By using white noise to mask any abrupt sounds, it prevents this response from being activated and helps to maintain a calm, relaxed state.

  • White noise machines: These devices come in various shapes and sizes designed explicitly for nursery use. They typically have multiple noise options, including white noise, to cater to your baby's preferences.
