But not all toys are good for children. Professor Wang Xijun of the Otolaryngology Center of Guangdong Armed Police Hospital pointed out that some toys can damage the child's hearing because of excessive noise, and some form irreversible hearing loss, which must be paid enough attention. Some institutions have tested the noise of seven types of children's toys (manned electric toy cars, spring sound toys, inertia toys, etc.), and the noise of manned electric toy cars is 74-97 decibels; toy vehicles, continuous shooting The cannons, etc., will have a noise of more than 80 decibels within 10 cm; there is also a large "music gun" with a noise of more than 110 decibels. Children are more sensitive to sound than adults. For example, some air-compressed toys that can be squeezed and squeezed have always been toys for parents to tease their babies, but the sound of the toy can reach 78-108 decibels within 10 cm, which will inevitably cause frightening to the baby. And damage the hearing. In addition, some children play submachine guns, cannons, tanks and other toys, within 10 cm, the noise will reach 80 decibels or more, playing for a long time will definitely damage the children's hearing. Professor Wang pointed out that there are 15,000 to 20,000 weak but very sophisticated "inductive receivers" in the human cochlea. Once they are damaged, they can no longer transmit sound to the brain, and this damage is mostly irreversible. The baby has a better hearing one month after birth. Because the auditory cells of the tympanic membrane, middle ear and inner ear of the child are very delicate, they are more sensitive to noise. If the noise of the toy exceeds 70 decibels, it will cause damage to the child's hearing system. If the noise often reaches 80 decibels, children may experience headaches, dizziness, tinnitus, emotional stress, and memory loss. Therefore, parents are choosing toys for their children. When you should consider the noise factor, don't blindly ask for new ones. If you want to blame, you should try to choose those puzzle toy types to avoid the children's high-noise environment such as tweeters and electric drills. The volume of the TV set and the recorder should be moderate, even if there is a home. Toys with loud noise should also be played as little as possible to reduce the harm that noise brings to children. For the hearing loss caused by noise, parents do not have to be too alarmed. They should go to a regular hospital for appropriate treatment, such as improving microcirculation, increasing neurotrophic nutrition and oxygen therapy. Children's hearing damage is relatively easy to recover. As long as problems are discovered early, treated and regularly checked, noise can be prevented from having a greater impact on the child's growth and must not be delayed.
A pellet grill is a type of outdoor cooking appliance that uses
compressed wood pellets as fuel to cook food. The pellets are fed into a
hopper, which then moves them into a burn pot where they are ignited by
an electric heating element. The heat generated by the burning pellets
is used to cook the food on the grill grates. Pellet grills typically
have digital temperature control systems that allow for precise
temperature regulation and cooking time. They are known for producing a
unique smoky flavor and are popular among barbecue enthusiasts.
