ABSTRACT:
A system for generating and delivering sound to a fetus or so-called "fetal child" through the mother's abdomen and which also allows for the monitoring of the effects of sound on the fetal child. The system comprises a belt adapted to be worn about the abdomen area of the mother and includes speakers located in the region of the fetal child for imparting sound through the abdomen wall to the fetal child. The speakers are connected to a sound generator, such as a tape recorder or the like. A stethoscope sensor is mounted in and carried by the belt and is also located in juxtaposition to the abdomen in proximity to the fetal child in order to determine the effects of the sounds on the fetal child. The stethoscope sensor is attachably connected to a stethoscope adapted to be worn by the mother or other user.
