Can children's earphones really protect their hearing? This problem is the most concerned problem of many users who buy children's headphones. We all know that wearing children's headphones is to protect children's hearing, but it can't protect children's hearing if it is not used scientifically.
Some medical data show that when the volume heard by human ears reaches 100 dB, it can cause unrecoverable hearing damage for a long time; When the volume reaches 110 dB, it is enough to kill hair cells in the human inner ear, and even cause hearing loss in severe cases. However, people's hearing loss starts from high-frequency hearing to low-frequency hearing. If the high-frequency level hearing loss can not attract people's attention and the noise pollution still exists, the level hearing of other frequency bands will have problems, which will slowly affect people's normal language communication.
What is hearing loss? Hair cells are auditory cells. There are 12000 outer hair cells and only 3500 inner hair cells. Most importantly, hair cell injury can not regenerate. Hair cell injury will affect the hearing of nerve parts of the cochlea. If the hearing has been damaged, it cannot be repaired, and the hearing can only go downhill.
Many children are exposed to various mobile terminals and learning machines and often use headphones. Children's headphones are mainly designed for children aged 6-12. The safe decibel control system can effectively protect children's ears. The range of human hearing is about 20hz-20000hz, and 60-85db is the best volume range for children's growth and development.
According to the latest data released by the World Health Organization under the United Nations, about 1.1 billion young people around the world are facing the risk of irreversible hearing loss. The principle of "60-60" should be followed when using only headphones, which is an internationally recognized method to protect hearing, that is, when using headphones, the volume should not exceed 60% of the maximum volume, and it is best to adjust it lower; The continuous use of headphones should not exceed 60 minutes. Do not use earphones when sleeping. Ear plugs are sandwiched between the pillow and ears, which will cause damage to the eardrum. If you listen to music and fall asleep, the damage will be more obvious when your ears are in a dormant state.
