White Noise: The Science Behind Soothing Sounds for Your Baby’s Peaceful Sleep

You are aware that sleep is very important for our babies. It is because sleep doesn’t only help our babies grow. It also ensures that they are happy and well-rested!

But sometimes, it’s hard to let our babies doze to sleep. Especially when there are a lot of external noises. There may be cars passing by, construction going on nearby, or other distracting sounds that may disturb our baby’s sleep!

White noise has been gaining popularity as a sleep aid for babies, and you may want to try this technique, too!

What is White Noise?

White noise contains all the audible frequencies humans can hear, making it a "uniform" sound that is consistent and constant. It is often described as a hissing, static-like sound likened to a television or radio tuned to an unused frequency.

White noise is generated by a white noise machine or a sleep sound machine, which produces a continuous and uninterrupted sound that can help mask other sounds in the environment.

How Does White Noise Help With Your Baby’s Sleep?

White noise helps create a masking effect that reduces other sounds your baby might find disturbing. The consistent background noise caused by white noise muffles sounds like your dog barking or your neighbor’s car honking.

White noise also creates a soothing environment for your baby. It mimics the sounds your baby used to hear while still in your womb, giving them a sense of security.

It also helps drown internal noise caused by the baby itself for better and longer sleep.

How to Use White Noise for Better Sleep?

White noise can be obtained from a sleeping device or a white noise generator that can be bought in the baby section.

Another option is downloading an application that plays white noise on your phone or tablet. This is a good option since it’s portable and can be used while traveling. Whether you’re looking for white noise for office purposes or white noise for public places, the portable white noise machine is the best sound conditioner for you.

It is recommended that the volume not exceed 50 decibels. This is similar to the volume of a hair dryer or normal conversation.

It's also important to safely place the white noise machine or device away from your newborn's ears, typically at least seven to ten feet away, to avoid any potential hearing damage.

Benefits of White Noise

The benefits of using a noise-canceling machine for your baby's sleep are numerous, including the following:

  • Helps your baby fall asleep faster and sleep longer.

White noise’s consistent and soothing sound creates a familiar environment for your baby. It helps them relax and drift off to sleep easily. It also blocks disturbing sounds that might wake your baby in the middle of the night.

  • Gives your baby a sleep routine.

Using a sound machine for sleeping creates a sleep association for your baby, signaling it's time to sleep. This can help your baby develop healthy sleep habits and improve their sleep quality!

  • Provides comfort to your baby.

Since white noise mimics the sound of the womb, it creates a sense of familiarity and comfort. It also helps your baby transition from the womb to the real world.

  • Benefits you as a parent.

You may be worried when you and your partner talk loudly. With a sound machine for your baby, you can do your daily activities that are quite noisy– vacuuming, watching TV, etc. without really disturbing your baby’s sleep.

Other Types of Good Noise For Your Baby

White noise is not the only sound that’s good for your baby. There are also other sounds to choose from, including the following:

Pink Noise

Pink noise is a deeper type of noise that’s bass-heavy. It usually has a softer sound and lower frequency. Pink noise can be compared to rainfall or ocean waves crashing onto the shore.

Pink noise has been found to be very soothing which can help your baby relax and fall asleep.

Brown Noise

Brown noise has an even deeper and richer sound compared to white noise. It has a lower frequency and rumbling quality, similar to a waterfall or thunderstorm sound.

Brown noise has been reported to be very soothing and can help mask external sounds more effectively.

Nature Sounds

Nature sounds like rain, ocean waves, or forest sounds are popular for sleep sounds. These create a calming and peaceful environment reminiscent of being in nature which can help your infant relax and fall asleep.

Womb Sounds

Some white noise machines or apps also offer womb sounds designed to mimic the sounds your baby heard while in the womb. These sounds can be comforting and familiar to your baby, helping them feel secure and calm.


White Noise for Babies - Is it Safe?

One common concern among parents is whether white noise is safe for babies. The good news is that white noise is generally considered safe for babies when used appropriately.

It is recommended that the volume of white noise should not exceed 50 decibels, so it should be about the volume of a regular conversation. 

It's also important to safely place the white noise machine or device from your baby's ears, typically at least 7-10 feet away, to avoid any potential hearing damage.

White noise shouldn’t be used as a substitute for safe sleep practices recommended by your pediatrician. White noise should only be used as a supplementary tool to aid in creating a good sleeping environment in combination with those recommended by your pediatrician.

White Noise Apps and Devices: Which To Choose?

When choosing the best white noise machine or application for your baby, plenty of options are available. You may consider these factors when making a choice:

Sound Options

Choose a sleep machine that has a lot of good sound options. If it has a variety of white noise, pink noise, nature sounds, and womb sounds to choose from, then that’s a good application.

With many sound options, you can experiment with which your baby loves the most!

Volume Control

Ensure that the white noise generator has adjustable volume control, allowing you to set the sound safely and comfortably for your baby's delicate ears.

Timer Settings

A good white noise machine has timer settings. Timer settings allow you to automatically set the time duration of when the sound plays. This helps in establishing a bedtime routine for your baby. You also don’t need to wake up only to turn it off!


Consider the portability of the white noise app or device. That’s especially if you travel with your baby frequently. Go for a portable white noise machine so that it’s easy to set up anywhere!

Ease of Use

Choose a white noise app or device that is user-friendly and easy to navigate, with simple controls and clear instructions. This ensures you can quickly set up and adjust the white noise to suit your baby's needs without hassle.

Safety Features

Check for any safety features, such as an auto shut-off after a certain period or overheating protection. Doing this will help guarantee that your investment in the white noise machine is secure and that you can use it safely and confidently for your baby.

Reviews and Recommendations

Read reviews and recommendations from other parents to understand the effectiveness and reliability of the sound therapy machine. Look for reputable brands with positive customer feedback and ratings.
