sleep machines could affect hearing, auditory development, study suggests  -  laser level meter
A new study in Canada shows that babies who are increasingly popular with their parents using white noise machines may put their children at risk of hearing loss.
If you follow the advice sometimes-
As the device approaches the child, the volume is loud and runs continuously-
Research notes that some machines exceed the noise limits set by occupational safety agencies for adults.
The authors believe that this noise may damage delicate ears and may even hinder auditory development.
"The potential impact on auditory development, speech and language development is theoretical at best," said senior author Dr . "
Blake Papsin, head of Otolaryngology, Toronto Children's Hospital.
"There are animal models in rodents that suggest this has happened.
But for young, developing, dealing with the brain, replace the whole concept of periodic, lovely, very complex ambient sounds with babbab's Creek, or "-
He made a still voice.
"It's stupid for me.
The study will be published in the journal Pediatrics on Monday.
The idea of researching a baby's sleep machine, like this series of products known as a baby's sleep machine, comes from an examination of a child who underwent surgery on a sick child.
When he walked into the patient's room, a sleep machine was running loudly.
Parents told the frightened Papsin that they were told to use the machine by sleeping Dura.
He left the room and took a student and a sound meter.
"In the room, she recorded 85 decibels.
Sound of car wash.
In the child's ear!
Cover up the noisy ward, which could be 85 decibels per se.
"I said," I'm going to study this. This is crazy.
His team bought as many different types of sleep machines as possible from baby stores and online channels.
They found 14 different models that could project various sounds such as Heartbeat, rain, waves and white noise.
They tested the maximum volume of each device at three different distances: 30 cm, which would be a typical distance from the baby when the device is connected to the baby bed Batten;
100 cms, which is like a surface placed near the crib, 200 cms, which is equivalent to passing through the room.
The occupational health standard stipulates that the noise of adult ears is 85 decibels for 8 hours;
After that, there may be hearing loss.
The exposure time allowed is halved for each three-point Bay that exceeds this limit.
So the exposure limit is 4 hours at 88 decibels.
No one has done research to figure out what safety exposure is equivalent to for young children, and no one can do such research.
This will be considered immoral.
But due to the physical properties of the baby's ears --
The small ear canal amplified the sound of a higher frequency
The neonatal intensive care unit recommends that infants be exposed to an average of more than 50 decibels within an hour.
Papsin and his team found that, except for one machine, it was more than 50 decibels at all three distances.
49 was registered with one exception. 2 decibels —
Then only at 200 cm. distance.
In fact, at 30 cm. —in the crib —
There are three devices that make more than 85 decibels, and one of them makes less than 93 decibels. At the 100 cm.
Machines above 60 decibels from all.
Sound level from 49. 2 to 76.
2 decibels at 200 cm. distance.
Papsin notes that these sound levels are in addition to any noise used for shielding.
"In philosophy, have we talked about this?
We are here as a society in 2014, do you need an app that embraces your children?
He asked doubtfully.
"Maybe if the baby beats to sleep comfortably, go to the crib and grab them and put them on your chest.
Installed using factory. Slow down here.
Let's talk about society.
Papsin may not be a fan, but a lot of young sleep
Poor parents.
They brag to friends about machines, buy machines for baby showers, and pass them out when their children grow up.
This is how Melanie Hunt uses sleep machines to help her two young sons, now 5 and 2, sleep.
When she was pregnant with her eldest son, a friend gave her and her husband a machine. “(They)
Swear by it, bought it for us as a gift.
"It became part of the sleep routine and even accompanied family members while they were traveling.
Does this help her child to sleep better?
"You will never really know," she said with a smile . ".
"You don't know if this is a placebo effect or just making parents feel like what this is doing. . . .
I just thought: well, it doesn't seem to be hurt.
If it helps, why not?
"We didn't start it," she added . " She noted that their device came with a timer that turned the machine off 15 or 45 minutes later.
Hunter just gave the sleep machine to a friend who was expecting her first child.
Papsin wants her and other parents who use these machines to pay attention to his findings and suggestions for research.
For parents who intend to use a sleep machine, they recommend that the device stay as far away as possible from the baby and not put it in a crib or connect to the baby bed.
He also urged people to use these machines in the shortest possible volume.
The study also suggests that manufacturers should take steps to make the machine safer.
These include warnings that limit maximum volume output, print the possibility of hearing loss on the package, and build timers in all models to program them to shut down after the set time.
