Baby sleeper engine in fact Hospitals Potentially Damaged Hearing

Toronto , In modern hospitals , rooms for premature infants or infants who were treated normally equipped machine baby sleeper . In the adult ear , this machine may not issuing sound like nothing, but for the baby , such a machine is even potentially damage their hearing .
Researchers discovered this fact after watching 14 baby sleeper that most machines sold in the U.S. and Canada . All 14 of the engine 65 can play the sound at maximum volume and researchers try memperdengarkannya from three different distances ; 30 cm , 100 cm , and 200 cm ( across the room ) .
It turns out that when turned dengen maximum volume, the researchers observed the entire engine noises exceed 50 decibels ( dBA ) , the standard limits the intensity of the sound of the engine is in the hospital , especially when placed at a distance of 30 cm and 100 cm .
In fact 3 of them reaching the engine sound levels exceed 85 dBA from a distance of 30 cm only . And if lit continuously for 8 hours , the intensity of these sounds more elevated and exceeded the sound barrier in accordance with the recommendation of the National Institute for Occupational Safety and Health for adult workers though .
Of the 14 machines tested researchers , there is only one machine that does not reach the level of 50 dBA , though placed at a distance of 200 cm from the baby .
Even one senior investigator in the study , Dr . Papsin Blake , head of the ENT division of the Hospital for Sick Children , Toronto said he also worried about the white noise can interfere with brain development of the baby recall baby needs to hear different types of sounds for the mature brain .
To the researchers urge parents to lose their baby sleeper engine volume or move the machine at least as far as 200 cm of the baby's hearing was not impaired in the future . If you need a baby sleeper engine standards must be raised as their own baby's ears are very sensitive , even more than adult ears .
" When we made ​​a model , from which we find that the estimated sound pressure level of security we use the following seems less attention , even though the baby's ear may be much more vulnerable than the adult ear , " said Dr. Papsin as quoted by CBS News, Wednesday ( 5/3/2014 ) .
