Music from toys can make children deaf

Some toys that make sounds for children can cause permanent damage to children's hearing, scientists from the Tai Institute, University of London (UK), warned.

'For most toys, children only have hearing damage when they use it for too long or when they attach toys to their ears. Our advice is simply: Don't let children hold toys that make sounds too close to their ears, and don't let them play those toys for longer than an hour a day ' - Dr. Brad Backus, team member save, say.

In the study, Backus tested the sound levels of the 15 most popular toys for children from 3 months to 15 years old. As a result, there are 8 types of toys that produce 81-105 decibels of sound if placed 25 cm from the ear, equivalent to the child's reach. If placed 2.5 cm from the ear, up to 14 toys emit 84-115 decibels.

Among these toys, toy guns have the loudest sound, 120-140 decibels in hand and 130-143 decibels when brought close to the ear. Meanwhile, the recommended maximum sound level is 85 decibels. If you hear sounds above this level for a long time, your child may suffer permanent hearing loss.
