But what exactly is white noise and why is it so popular? This article explores the effect of white noise on baby's sleep, its benefits, limitations, and precautions to take.
What is white noise?
White noise is defined as a consistent, consistent sound that covers all audible frequencies, creating a relaxing atmosphere that helps calm and lull babies back to sleep when they are upset. Think of the hum of a fan, the sound of light rain falling, or the sound of wind blowing. Unlike sudden noises that can disrupt sleep, white noise creates a stable soundscape. This type of sound masks ambient noises that might wake your baby, creating an environment conducive to sound sleep .
There are several types of noise:
- White noise : It includes all sound frequencies at equal intensity, similar to the sound of a television with no signal.
- Pink noise : Less intense at high frequencies, it is perceived as softer and more natural, like the sound of waves.
- Brown noise : With lower frequencies and a deeper sound, it is reminiscent of distant rumblings of thunder.
For babies, white noise is often preferred because of its ability to replicate the in-utero sound environment, an environment they associate with safety and comfort.
Why does white noise help babies sleep?
A calming and reassuring effect
White noise, which is a range of constant sound frequencies, mimics the intrauterine environment in which the baby spent nine months. During this period, the fetus is exposed to the regular sounds of its mother's body, such as heartbeat and blood flow, which form a kind of "background noise". Thus, white noise sounds remind newborns of this familiar environment, which helps them feel safe and reduce their anxiety about unfamiliar stimuli from the outside world.
Reduction of night awakenings
Background noises like a door slamming or a dog barking can cause micro-awakenings . White noise masks these sudden sounds, helping to maintain deep sleep throughout the night.
Creating a Sleep Routine
Regular use of white noise can help establish a positive association with sleep. By turning on white noise before naptime or bedtime, babies quickly understand that it is time to rest. This association becomes a reassuring cue in their routine.
Establish a wake-up and sleep routine
Using white noise regularly before naptime or at bedtime helps establish a routine. By associating this sound with a sleep ritual such as reading a story or brushing teeth, the child understands that it is time to go to bed , promoting a relaxed awakening and better preparation for sleep.
Improving sleep quality
Studies have shown that white noise can improve sleep quality in infants. A study published in the Journal of Pediatrics found that 80% of babies exposed to white noise fell asleep within five minutes , compared to only 25% in a quiet environment.
The different types of white noise for babies
The range of white noise devices is vast, and every family can find a solution that suits their needs.
White noise machines
These specialized devices or white noise toys offer a wide range of sounds (rain, waves, heartbeats). Easy to use, they often have timers and volume settings, which allows you to customize the experience according to the child's preferences. Many brands offer equipped stuffed animals of devices emitting white noise. These soft toys are designed to be placed near the baby, while being safe for prolonged use. Some also offer the night light option. They are practical because they can also become a comfort blanket or an object of comfort for the child. A nice idea for a birth gift to improve their sleep!
Mobile apps and playlists
There are many apps and playlists dedicated to white noise , available on smartphones and tablets to facilitate sleep. These solutions are practical, economical and allow to bring relaxation wherever the baby goes.
Natural solutions
Some parents prefer non-electronic solutions, such as the hum of a fan, the sound of a hair dryer , a vacuum cleaner , or the soft sound of a humidifier. These devices have the advantage of being multifunctional while producing a constant, soothing sound.
What is the best white noise for babies?
The best white noise for your baby depends on their personal preferences. Some babies respond well to nature sounds, like rain or waves, while others prefer mechanical sounds like a fan. It can be helpful to try a few different types of noise to see which one works best for your child.
At what age should you stop white noise?
There is no set age to stop white noise . However, it is recommended to gradually reduce the use of white noise as your baby gets older, usually around 12 to 18 months of age. This allows the child to get used to falling asleep without this stimulus.
How long should I play white noise on my baby?
It is advisable not to let white noises run continuously all night. You can use them during the falling asleep phase ( about 20-30 minutes ), then gradually reduce the volume or turn them off once your baby is deeply asleep.
Please note: To ensure your baby's safety , it is important to place the source of white noise at least one meter away from his crib, and to keep the volume at a low to moderate level. This helps prevent potential damage to his hearing.
What are the precautions and limitations of using white noise?
Despite its benefits, prolonged exposure or excessive dependence can be problematic. It is therefore essential to reduce its use gradually so that the child learns to relax and fall asleep independently. Around the age of 12 to 18 months, it may be wise to reduce the use of white noise to facilitate a natural transition to sleep without sound aids.
Prolonged exposure
Excessive exposure to high volumes can pose a risk to a child's hearing. Experts recommend keeping the volume below 50 decibels , a level comparable to a normal conversation.
A habit
Some babies may become dependent on white noise to fall asleep, which can make it difficult to sleep without it. It is therefore advisable to gradually reduce its use once the child has acquired good sleeping habits.
Directions for use
- Place the sound source at least one meter from the baby's bed .
- Use a timer to avoid continuous exposure all night.
- Experiment with different types of sounds and melodies to find the one that works best for your child.

By incorporating these precautions and combining white noise with an evening ritual that includes bathing, cuddling, massage and story time, you will contribute to a more peaceful sleep for your baby , helping the child to wake up rested and ready for the day.
