With the improvement of material living standards of the people, all kinds of household appliances have entered every household. When people fully enjoy these modern civilizations, they have also tasted the various hazards they bring to the human body. Family noise is one of them. According to the scientists, the noise generated by television sets and tape recorders can reach 60 to 80 dB, the washing machines 42 to 70 dB, and the refrigerators 32 to 50 dB. The relevant state standards, residential area environmental noise, daytime can not exceed 50 decibels, the night should be less than 45 decibels, if more than this standard, it will be harmful to the human body. Especially children, because of their growth and development stage, the tissues and organs are very delicate and fragile, therefore, the noise on their more serious harm. Medical experts believe that family noise is one of the causes of deafness in children. According to clinical medical statistics, if the life in the noisy environment of more than 80 dB, resulting in up to 50% of deaf-mute. In addition, children often in a noisy environment can reduce the diopter and sensitivity of the eye, pupil
