What you don’t know about white noise that could hurt your child


More than half of Americans use some sort of background noise to help them fall asleep. People use tools like box fans, YouTube videos and designated white noise machines to drown out interruptions that could disturb their sleep. For new parents, the machines can help them, and their newborns, get a good night’s sleep.

However, new research shows many of the white noise machines available are potentially too loud for infants’ ears. A study published in Sleep Medicine measured the decibel levels of 24 white noise machines and apps. None of them are federally regulated.

The study found the devices did not have a decibel cutoff. Research showed a cutoff is necessary to safeguard their children’s hearing.

“Those devices exceeded what is appropriate for hearing health for any individual, just walking around and living their life,” researchers told ABC News.

A separate study by behavioral scientists found that white noise could even be the wrong “color” of noise for sleep. The spectrum of color noise classifies everyday noises and frequencies into colors. A running fan is considered white noise. Blowing wind is pink noise and the rumble of distant thunder is brown noise.

In a recent study researchers found white noise is a harsh frequency that “wakes the brain.” It acts as a stimulant, with minor improvements in task performance.

The researchers suggested if a person chose to use noise while they sleep, they should use pink noise. It is the color that more closely resembles frequencies the brain gives off during sleep.

However, evidence showed that using noise, like many other sleep aids, can be addictive and lead to poor sleep habits. Experts also said stopping any sleep aid cold turkey can have negative effects on everyday sleep quality.

The recommended method to wean a person or their child off of white noise is to decrease the volume incrementally until they no longer need it to sleep.

[WHITE NOISE]

IT’S A FAMILIAR, SOOTHING SOUND.

[WHITE NOISE]

[KARAH RUCKER]

MORE THAN HALF OF ALL AMERICANS USE SOME SORT OF BACKGROUND NOISE TO HELP THEM FALL ASLEEP.

FROM BOX FANS TO YOUTUBE, OR EVEN DESIGNATED WHITE NOISE MACHINES – THE POINT IS TO DROWN OUT UNWANTED INTERRUPTIONS THAT MIGHT DISTURB OUR SLEEP.

AND FOR MANY NEW PARENTS – THESE MACHINES CAN BE A LIFESAVER. 

BUT NEW RESEARCH SHOWS A HOST OF WHITE NOISE MACHINES ON THE MARKET ARE POTENTIALLY TOO LOUD FOR THE EARS OF INFANTS. 

A RECENT STUDY PUBLISHED IN THE JOURNAL SLEEP MEDICINE, MEASURED THE DECIBEL LEVELS OF 24 WHITE NOISE MACHINES AND APPS. 

ALL OF WHICH WERE NOT FEDERALLY REGULATED. 

THE STUDY FOUND THE DEVICES LACKED A SPECIFIC DECIBEL CUTOFF –

A NECESSITY FOR PARENTS LOOKING TO SAFEGUARD THEIR CHILDREN’S HEARING.

THE AUTHORS OF THE STUDY TELLING ABC NEWS, “Those devices exceeded what is appropriate for hearing health for any individual, just walking around and living their life.”

A SEPARATE STUDY BY BEHAVIORAL SCIENTISTS FOUND THAT WHITE NOISE COULD EVEN BE THE WRONG “COLOR” OF NOISE FOR SLEEP.

THE SPECTRUM OF COLOR NOISE CLASSIFIES EVERYDAY NOISES AND FREQUENCIES INTO COLORS.

A RUNNING FAN IS CONSIDERED WHITE NOISE, BLOWING WIND IS PINK NOISE, AND THE RUMBLE OF DISTANT THUNDER IS BROWN NOISE.

IN A RECENT STUDY, RESEARCHERS FOUND WHITE NOISE IS A HARSH FREQUENCY THAT “WAKES THE BRAIN,” ACTING AS A STIMULANT, WITH MINOR IMPROVEMENTS IN TASK PERFORMANCE.

THE RESEARCHERS SUGGEST IF YOU CHOOSE TO USE NOISE WHILE YOU SLEEP, USE PINK NOISE, AS IT MORE CLOSELY RESEMBLES THE FREQUENCIES YOUR BRAIN GIVES OFF DURING SLEEP.

HOWEVER, THERE IS EVIDENCE SHOWING THAT USING NOISE, LIKE MANY OTHER SLEEP AIDS, IS ADDICTIVE, AND CAN LEAD TO POOR SLEEP HABITS.

AND EXPERTS SAY STOPPING ANY SLEEP AID COLD TURKEY CAN HAVE NEGATIVE EFFECTS ON YOUR EVERYDAY SLEEP QUALITY.

THE RECOMMENDED METHOD TO WEEN YOURSELF OR YOUR CHILD OFF OF WHITE NOISE IS TO DECREASE THE VOLUME INCREMENTALLY UNTIL YOU NO LONGER NEED IT TO SLEEP.
