Four kinds of noise damage in life, baby hearing

1, toy noise

A variety of colorful electric toys , while inspiring the child's intelligence, too loud sound, may cause sound damage to the child's hearing. Experts remind that when buying toys for children of young age, you must carefully select them, and do not harm children without knowing them. The following set of toy noise test data can roughly reflect the toy noise pollution that children face:

The noise emitted by toy vehicles is 82 to 100 decibels within a distance of 10 cm;

Large music guns have a noise value of 74 to 107 decibels at a distance of 100 cm and a maximum of 130 to 140 decibels;

An air compression toy that is squeezing and squeaking can reach a volume of 78 to 108 decibels within a distance of 10 cm;

The manned electric toy car has the highest sound level, reaching 74-97dB (decibel). These toy cars are mostly found in children's playgrounds in parks or large shopping malls.

Prevention:

When choosing a toy for a child, be sure to pay attention to the physical and mental development and health of the infant. The sound of the toy should be controlled below 70 decibels. First, buy regular toys. For example: toys should be able to pass safety and qualified monitoring. Toys that are scoured from the wholesale market are not safe, so don't consider them; second, screen the toys. Before the child gets the toy, parents should first listen to it about 30 cm away from their head. If you are all shocked, its volume will definitely exceed the standard; when in use, control the volume of the toy. If it is too noisy, it is recommended to stick the speaker with a strip to reduce the volume, or simply take the battery out. Keep your time as short as possible when playing video games or listening to stereo equipment.

In addition, children should be allowed to eat coarse grains, peanuts, soybeans and fish, meat, eggs, milk and other foods rich in B vitamins and protein to prevent hearing loss.

2, living environment noise

Experts caution that some of the hard-to-find noises in the living environment are damaging our hearing, including noise in the home environment. The noise of the home environment mainly comes from some household appliances, the surrounding environment of the home, etc., and the damage of noise can be appropriately mitigated by knowing the decibel value of various sounds.

National limits for various household appliances noise:

Air conditioning: according to the cooling power, the air conditioning noise limit is 40 decibels to 68 decibels;

Washing machine: The washing machine has a maximum washing noise limit of 62 decibels and a dehydration noise limit of 72 decibels;

Refrigerator: A refrigerator with a capacity of less than 250 liters has a noise limit of 45 decibels to 47 decibels; a limit of 250 liters or more is 48 decibels to 55 decibels.

Microwave oven: The microwave oven has a limit of 68 decibels.

In addition, the standard requires refrigerators, air conditioners, washing machines, microwave ovens, range hoods and electric fans six categories of home appliances on the nameplate or instructions for use must be marked with noise values, otherwise it is not allowed to go on sale.

Prevention:

Devices with loud noise in the home should not be turned on at the same time, and the children should avoid being in a noisy environment for a long time, avoiding the common sources of noise pollution in life, such as TV, or high-volume stereo. When there is a long period of noise around the child, for example, when there is a sound of decoration next door, parents should give the child an earplug that protects the hearing or take the child away from the source of pollution. In addition, if the environment around the home is noisy, you can do some sound insulation in the room decoration and layout: you can choose thicker curtains, some soundproofing materials can be used for door and window and wall decoration; choose quiet heating and ventilation equipment; Keep your child in the room as little as possible from outside noise.

3. Noise at the playground

Relevant information shows that in entertainment venues such as shopping malls, amusement parks, theaters, etc., the environmental noise is often seriously exceeded. According to the existing monitoring, some children's playgrounds often have noises above 85 decibels, and even up to 96 decibels. The environment, children's hearing will be severely damaged, and various bodily functions will also be affected.

Prevention:

Try to take fewer children to the more noisy playgrounds, or shorten the time spent in the playground. For more noisy rides, choose to wear hearing protection devices such as earplugs or earmuffs, and shorten the time of play. Parents are advised to take their children to some quiet activities, such as reading, parent-child games, painting, educational computer games, etc., or visit a library, art gallery or museum. These activities or environments not only reduce noise exposure. Opportunities also benefit the development of children's ability in all aspects.

4, parents quarrel noise

In addition to the external noise, the parents' quarrel will also bring the baby "psychological noise." After 6 months, the baby will form a family concept and know that he and his parents belong to a small group. This is why the baby is naturally intimate with his parents. However, when parents are quarreling in front of their children, the baby will find that the parents' voices are particularly harsh. This kind of quarrel breaks the original harmony, which is inconsistent with the family concept in his heart. Therefore, in order for the baby to have healthy emotional and EQ levels, parents should "create" this "psychological noise" for the baby as little as possible.

Special reminder: Some studies have shown that children are more sensitive to sound perception than adults. More than 70 decibels of noise can damage a child's hearing system. When the noise reaches 80 decibels, children will have various hearing impairments. problem.
