Why chief of staff turned Lieyan master?
Injury grassroots civil servants are all our library of asymmetric information, there is a prenatal music and noise problems, divided into two areas, one is pure noise, but also most of the time who do not like the sound. Another is to create their own voice, car food warmer sometimes, we want to hear the sound, but sometimes they do not want to hear. Silver fiber radiation suit Indeed, both of which are defined according to their preferences. As a mother station. We also mainly to pregnant women and children. For example. If the mother is exposed to high noise environment, you may have a detrimental effect on the development of the fetal ear these things, first in Poland and the United States, attracted people's attention. Very common especially in the form of textile industry and aviation industry noise conditions, the impact of fetal auditory system, the human fetus to obtain data for the first time. Fetal auditory effects of noise exposure on the last 75 of 10 - children under 14 years of hearing tests, their mothers during pregnancy, exposure to noise at least 100db mills, found that half of children with hearing loss, which may be due to fetal exposure As a result, hearing loss, and 71% at high frequencies (ie 71% of the children in their ears to hear high frequency sounds). The impact of noise on hemispheric specialization living fetuses and children daily in order to study the effects of noise suppression mechanism of fetal growth, but can not afford the aircraft noise 22-41 weeks of gestation maternal serum placental progesterone (conducive to fetal growth substances) measurement results show , in a quiet area and high Early region, after 29 weeks of pregnancy, placental progesterone secretion similar, but the thirtieth week high noise area survey placental progesterone secretion decreased placental progesterone secretion, and low natural pregnant women, infants low birth weight. Environmental Noise seven - 10 years old children's brain development, is still an open question. To study the problem of high noise and quiet children living in different mental tasks, the task of the left hemisphere and right hemisphere were studied, no stimulation, the right hemisphere dominant noise stimulus, a series of meaningful music sound stimulation to stimulate the left hemisphere. Practice car food warmer has proved that the efficiency and speed of the noise will be slow, slow, personally think that inattention problems, irregular noise during operation we will attract a half a second, then turned to the brain data re- computer-controlled equipment, which is not good. Children and pregnant women, but also a consequential damages, so the noise can be avoided. Noise, who will not give up. Radiation suits really helpful Send comments |
