Children than adults of sound sensitive sensor.
For example, some after extrusion compressed air can squ eak toys, parents always tease the baby\'s toys, but the toys in 10 cm up to 78 within a squeaky sound to 108 decibels, which will inevitably result in the baby frightened, and hearing damage. In addition, some children playing with assault rifles, artillery, tanks, trucks and other toys at 10 cm within the noise will reach 80 decibels or more, for a long time to play will certainly damage hearing of children.

One month after the baby had been born with a better hearing, because children\'s eardrum, middle ear, inner ear\'s auditory cells are very delicate, it is more sensitive to noise. If the toy noise exceeded 70 decibels, the child\'s auditory system will cause damage. If the noise often reaches 80 decibels children will produce headache, dizziness, tinnitus, emotional stress, memory loss and other symptoms. Therefore, parents give their children sho uld be considered when selecting toys noise factor, not blindly novelty, strange, you should try to pick those puzzle toy breed, avoid touching children tweeter, drill high noise environment, put televisions, tape recorders The volume should be moderate, even at home with noisy toys, but also to play sparingly in order to reduce the noise to the child harm.
