Babies like to listen to people’s voices and dislike the interference of noise.The most direct harm of strong noise to the fetus is that it may have adverse consequences for the fetus’s auditory development.In addition, long-term exposure to noise can cause dysfunction of the endocrine glands of pregnant mothers, causing strong uterine contractions, which may lead to miscarriage and premature delivery.If the inner ear of the fetus is stimulated by high-intensity noise for a long time, some areas of the brain will be damaged, which may affect the development of the brain in severe cases.Studies have shown that the baby’s personality may be more irritable in the future when exposed to noise for a long time.
