What is White Noise?Updated 2 months ago

White noise is a sound that combines all audible frequencies at equal intensity, creating a consistent, steady noise without a specific pitch. It often sounds like a soft, fuzzy hum, static, or a hissing sound.

For infants, white, pink, or brown noise can be helpful by masking distracting sounds in the sleep environment—like doors slamming, loud conversations, or barking dogs—helping to create a more peaceful and calming atmosphere. It can also act as a sleep cue, signaling to your baby that it’s time to sleep, and soothe them with familiar, gentle sounds.

When used safely, white noise can be a useful sleep aid from birth, supporting your baby in staying asleep by blocking out disruptive external noises.
