Shocking, Scientists show that Unborn babies are able to hear in the womb at just 16 weeks
gestation, For the first time scientists at the Institut Marques in
Barcelona have shown a foetus is able to detect sounds, and furthermore, that
they respond by moving their mouths and tongues.
It is accepted that an unborn baby's ear is fully developed
at week 16 of a pregnancy.
But, until now experts did not believe a foetus could hear
until week 18, at the earliest but more commonly nearer 26 weeks.
Dr Marisa Lopez-Teijon, who led the study, said the findings
show a foetus responds to music transmitted intravaginally by moving their
mouth and tongue, 'as if they were trying to speak or sing'
While showing for the first time that foetuses hear as early
as 16 weeks, the study also has wider implications.
Researchers note their method could be used to rule out
foetal deafness, and allows the parents to ensure foetal wellbeing.
The music stimulates the part of the brain involved in
communication, and on hearing the sound the foetus responds with movements
similar to vocalisation - the step prior to singing and speaking
Using the device, known as a Babypod, developed for the
study, mothers could begin to stimulate their unborn baby's communication
skills before they are born.
In essence, it suggests babies can begin to learn before
they are born.
The experiment was carried out on pregnant women between the
14th and 39th week of pregnancy.
Throughout the study, the team used ultrasound to observe
the reaction of the foetus, after hearing music.
The music was emitted both abdominally - against the bump -
and intravaginally, via a special speaker inserted into the vagina.
The foetus's were all played Johann Sebastian Bach's Partita
in A Minor.
