Understanding White, Brown and Pink Noise for Children's Sleep

Gentle background sounds can help children fall asleep easily and stay asleep longer, according to parents, and backed by research studies. These sounds work by creating an environment that masks environmental noises, like doors closing or sirens blaring, that might otherwise wake a child. Consistent use of calming noise can be a helpful and healthy part of a child’s bedtime routine.

White Noise

White noise sounds like a steady "shhh", like a fan or radio static. It includes all sound frequencies at equal intensity, which makes it great at blocking out unpredictable noises. Many baby sound machines use soothing white noise.

Brown Noise

Brown noise is deeper and more rumbling, like a waterfall or thunder. It has lower frequencies and can feel more calming for children who are sensitive to high-pitched sounds. Some kids find this lower tone more comforting and sleep-inducing.

Pink Noise

Pink noise is a balance between white and brown noise. It still contains all frequencies, but emphasizes the lower ones, making it softer, like rainfall or wind rustling through trees. Some research suggests pink noise may promote more stable, deeper sleep.

Which Is Best for Your Child?

Every child is different. Some may prefer the brighter sound of white noise, while others may respond better to the deeper tones of brown or pink noise. It's safe to try different types and observe which one helps your child settle best. Always keep the volume low and place the sound machine away from the crib or bed.
