1. Avoid noise pollution. Infants' hearing organs are underdeveloped, and too much sound stimulation will do harm to hearing. So try to avoid exposing children to too noisy environment.
2. Reduce the use of headphones. Using headphones for a long time will do harm to children's hearing. If you must use headphones, choose products with low volume and low frequency, and do not exceed 2 hours a day.
3. Check your child's hearing regularly. It is recommended to take children to the hospital for hearing examination every year, and find problems and take measures in time.
