Babies tend to like white noise. That could be because they are used to it. Before making their grand debut, your baby spent their days and nights awash in the reassuring hum of human life. A beating heart, the sound of the blood rushing around the body, and the rhythmic in and out of every breath created a comforting cacophony somewhat akin to the roar of a vacuum.
For comparison, the "shushing" sounds in utero range anywhere from 72 to 88 decibels, while a vacuum cleaner is about 70 decibels. In other words, the womb is not a quiet place!
Once born, your little one suddenly finds themself in a disconcerting world of hushed tones and measured steps. Although designed for their comfort, this carefully guarded silence can leave them feeling detached, anxious, and isolated. No wonder your baby might be having trouble sleeping. That's where white noise may come in handy.
Why White Noise Can Help Your Baby Sleep
White-noise machines create a comfortable, womb-like environment that calms infants, encouraging them to stop crying andfall asleep faster. Research shows they can also help children perform certain tasks that may be impacted by attention-deficit/hyperactivity disorder (ADHD), such as speech recognition.
White-noise machines also help babies stay asleep longer. It may seem like it works like magic, but the trick can be easily explained.
Ever wonder why your baby seems to sleep for only 20 minutes at a time? As your little dreamer snoozes, they cycle in and out of deep sleep and light sleep, experiencing brief periods of what's often referred to as “sleep arousal” about every 20 minutes or so. Babies wake easily during these periods of light sleep and become anxious, leading to a premature end to naptime.
White noise can help silence your baby's built-in 20-minute alarm clock by drowning out doorbells, rambunctious siblings, and other potential disturbances during vulnerable phases of light sleep. Should your baby begin to stir naturally, the calming drone of the white-noise machine could provide a source of comfort, encouraging them to sink back into a deep sleep.
How To Buy a White Noise Machine
If you want to buy a white noise machine to help your little one sleep better, it's important to take a few things into account, including noise limits.
The American Academy of Pediatrics (AAP) warns against several white-noise machines, citing that anything above 50 decibels could cause damage to a baby's hearing as well as cause other developmental delays.So, before purchasing a white noise machine, be sure you do your homework to ensure your little one's safety in terms of noise levels.
Another potential pitfall: Battery-operated machines or machines that only work on a timer. Many babies will wake when their machine stops working, so choose a model you can leave on all night if need be.
White-noise machines are available online and in most stores. But if you're on a budget, white noise is also easy to produce at home, such as by running a fan. You also can pick up a free, whitenoise-generating app, such asWhite Noise Baby, for your smartphone—a great, on-the-go option.
How To Use a White Noise Machine
Now that you've settled on the right machine, you're probably wondering how best to use it. What volume works best? How loud is too loud?
You may have to adjust the volume on your white noise machine in order for it to effectivelycalm down your crying baby. Once your little one has been soothed, adjust the volume to the level of asoft shower. If it seems uncomfortably loud to you, be sure to turn it down, as your little one may be uncomfortable also.
Along with avoiding the maximal volume setting, research also shows it's best to keep white noise machines at least about a foot away from the child.
It's also a good idea to always consult your child's health care provider before using a white noise machine or any white noise machine alternatives.
