The most important thing is the harm caused to the hearing of the fetus. The noise received by the fetus is transmitted through the mother's abdominal wall, and when a pregnant woman's abdomen is exposed to strong noise, it exposes the fetus to strong noise as well. Although the various tissues of the mother's abdominal wall, the uterus, amniotic fluid and other tissues and structures, can play a protective role in fetal hearing, but the effect is very limited, especially for low-frequency sound, almost no attenuation of the function, which is equivalent to the fetal sense of hearing directly with the strong noise contact. Fetuses are very sensitive to noise damage because the cochlea and other structures have not yet reached structural and functional maturity, so their hearing is very sensitive to noise damage. In addition, exposure to high levels of noise during pregnancy may result in intrauterine growth retardation and low birth weight. It is also now recognized that noise stimulation of the inner ear of the fetus can damage parts of the brain and severely affect brain development, leading to low intelligence in the infant or child after birth. To avoid working in the environment where the noise intensity exceeds the national health standard; watching TV and listening to stereo should ensure that the sound intensity is moderate; consciously avoid dance halls, construction sites and other places with high noise intensity; it is best to keep a long distance from the ear-splitting and continuous firecrackers during the Chinese New Year; and the use of fetal music should meet the requirements in terms of frequency and sound intensity, so as to protect the healthy development of the fetus. On the other hand, it is also necessary to prevent the tendency of emotional tension due to over-vigilance.
