In the study, researchers from the University of California, the United States analyzed the 10 most popular loud toys and came to a disappointing conclusion that many of them simply can not be sold, because these products are made noise decibels equal to sensations from a trip on the subway.
Top 3 most dangerous high-profile toy looks like this:
1. Fire engines
2. Superschit Captain America (producer of Marvel)
3. Cannon Green Lantern.
"When used properly, these products are safe for children, - says professor of otolaryngology Hamid Daylilian - but because the child does not always listen to the advice of adults, and he will want to bring rustling the product closer to his face."
Toys, loud noise, tested by scientists at a distance of 12 inches from the speaker (this is the average length of the child's hands). At such a distance from the hearing holes they are safe. But if the children are very sensitive to loud noises or toddler toy brings to his ear, it can easily lose your hearing, and so far in this case, the medicine can not help.
According to the Center for prevention and control of diseases, exposure to sounds at 85 decibels is already harmful for small ears, and the higher the noise level, the more likely that eventually the child will be deaf. The longer the noise exposure, the worse, because irreparable damage is done faster.
• 140 decibels: Loud children's toys That simulate the sound of gunfire
• 120 decibels: The siren fire engine or ambulance
For comparison:
• 100 dB: Noise Underground
• 90 decibels: mower, hair dryer
• 80 decibels: A telephone call, the noise of the street transport
• 60 dB: Ordinary conversation
• 40 decibels: Buzz refrigerator
• 30 dB: Whisper
If your baby squealing with delight at the sight of sound toys you can buy it, but only if you check the level of its volume and ponazhimat all keys. If a sound will seem unpleasant, so for the baby's ears, it is contraindicated for 100%.
