The embryo can hear music and appreciate that music has been an endless debatable problem for long time.The supporter thinks that the embryo can not only hear music but also appreciate music, so prenatal influence is carry on excellent living excellent teach essential to have of form and contents.The opposite thinks then that the embryo can hear and appreciate that music doesn't have strict science fact and experiment to verify, say that the embryo can hear and appreciate that music is only the theories which hasn't yet a confirmation and what to benefit is company's house and what to victimize is a pregnant woman and embryo.More someone think and music prenatal influence is only false science or company's house to invent and used for profitable speak.
In fact, the embryo can hear and appreciate that music really has no strict science research to take in to confirm.To clear up this problem to want to make a little bit pure basic science principle first also need to combine some results of the latest research analytical.
Is the first problem an embryo and can hear orotund?This problem seems to be not difficult resolve, this be decided by:Sensory apparatus while being an embryo-brain and inner ear whether growth takes shape with maturity.Affirmative to this question answer.The fertilizied egg grows up to around 4 weekses and the ear bubble then starts become.To 20~22 weeks, the embryo's inner ear has already grown up adult's size.The then basic maturity of the auditory nerve system of 6 month embryos.Two is an orotund dissemination.The voice wave that the person can hear vibrates between 20-20000 Hertzs and this is different in the dissemination speed in the different medium.In the air, muscular tissue and water, voice wave the speed of the dissemination distinguish to 343 meters/ per second, 1775~1785 meters/ per second and 1450 meters/ per second.This is to say, the voice dissemination with up in the air wave is most slow, in the muscular tissue spread most quickly, in the center of is water.The embryo wants to hear orotund and have to lie quality-air, maternal belly and womb muscular tissue and water(amniotic fluid) through these three kinds of orotund disseminations.Because the voice wave is here three kinds of mediums in can spread, so the second condition also establishes.So we can get a conclusion:Sense of hearing and nervous system develop a mature embryo and can hear outside voice.
But, the embryo can appreciate music and this was a more complicated problem.Because the voice is different in the dissemination speed in the different medium, floating melody through toss about of a few mediumses after by all means and greatly give discount, volume, sound quality, pitch and sound's aring strong will take place variety.Through the refract of the muscle and the amniotic fluid and the absorption's music affirmation after spread outed of shape, they may become some voices that can hear, and the pole be probably to listen to not that clear voice or Zao voice.A research of American researcher gave confirmation to this.
