INVESTIGATION OF ACOUSTIC FIELDS ACTING ON THE FETUS IN THE MOTHER''S BELLY
It is known that a baby in the mother's belly hears the voice of the mother and reacts to it. The latest investigations on antenatal development of human embryos revealed new possibilities for sustaining the development of a baby prior to its birth based on sound communication of the mother with her baby. Numerous attempts have been made to deliver external sounds, namely music, the mother's voice registered using recorders, voices of strangers, etc., with an aim to evaluate their effect on pre- and postnatal psychological development of a baby. In this case, the parameters of acoustic signals are usually not normalized and not measured that can be dangerous for the fetus and hinder the estimation of their cognitive effect. This work is aimed at developing a device ensuring the delivery of informative acoustic signals with normalized physical characteristics.
