The notion that the child begins to relate to its environment before birth could accelerate and improve upon any learning that is associated with hearing. Brown's findings build upon a 1989 study by Kenneth Gerhardt, chairman of UF's Department of Communication Processes and Disorders, and Robert Abrams, a professor in the College of Medicine's Department of Obstetrics and Gynecology, that found that a fetus is exposed to certain low frequency noises. Brown joined that research team in 1990 and found that 60 percent of what is spoken at normal conversation level can be heard from inside the womb. To accelerate language learning, parents could, for example, read to a fetus, Brown said.
Most children only learn to speak a few words during their first year.
But, if parents communicate with an unborn child, some may develop a better foundation for learning speech and language. Ultimately, talking to a fetus could result in better skills and fewer learning disabilities. So any learning paradigms that require a child to use his hearing could be used before birth. But the fetal ear's sensitivity to noise from the outside world should also be a warning to parents, Brown said. The researchers are concerned that low frequency noise or excessive vibration might possibly damage the hearing of fetuses.
