All kinds of toys to increase the laughter of childhood life, not only the development of intelligence and mental pleasure. However, I wonder if the parents caused enough attention, many toys will borrow noisily to attract children, and this long-term noise may be silently swallowed hearing children's health and may have disastrous consequences. After squeezing the air compression can squeak toys, parents always tease the baby's toy, but these toys in 10 cm squeaky sound within reach 70-100 decibels, equivalent to a tractor in the ear ring, which did not prepare for the baby, they will be frightened, hearing damage. Children's toy vehicles, bursts of cannon, etc., in 10 cm, the noise will reach more than 80 decibels. There is also a large "music gun", the noise of 110 dB or more serious cases, and jet noise considerably.

40 db below the sound without adverse effects on children, 80 decibels loud sound will make children feel uncomfortable, if the noise often reaches 80 decibels children will produce headache, dizziness, tinnitus, emotional stress, memory loss and other symptoms. Healthy growth of infants and young children, need a quiet and comfortable environment. Some child psychologists, child protection experts, environmental experts have called for, children's toys toy manufacturers must pay attention to the noise on infant hearing hazards. Young parents and grandparents in the selection of toys, they must be careful and thoughtful, do not forget the noise on the negative effects of hearing infants.
