A Doppler fetal monitor, informally known as sonicaid (generic trademark), is a hand-held ultrasound transducer used to detect the fetal heartbeat for prenatal care. It uses the Doppler effect to provide an audible simulation of the heart beat. Some models also display the heart rate in beats per minute (BPM).

Obstetric ultrasonography, or prenatal ultrasound, is the use of medical ultrasonography in pregnancy, in which sound waves are used to create real-time visual images of the developing embryo or fetus in the uterus (womb).
The head is directed to the right in the image. The heart is discerned in the center of the embryo. A hand is visible slightly above. Even before the fetal stage begins, a six-week-old human embryo can arch its back and neck. [6] By seven weeks, movement in the arms and legs can be detected by ultrasound. [6]

It has also been described as a sharp, whistling sound that is synchronous with the pulse of the foetus, usually heard during the second trimester of pregnancy (13–28 weeks). [3]
Also, most low-frequency sounds (less than 300 Hz) can reach the fetal inner ear in the womb of mammals. [20] Those low-frequency sounds include pitch, rhythm, and phonetic information related to language. [21] Studies have indicated that fetuses react to and recognize differences between sounds. [22]
"The baby did not reach out," Dr Bruner said. "The baby was anesthetized. The baby was not aware of what was going on." [7] The surgeon who operated on the mother stated that rather than the fetus' hand clutching on to his finger, he was simply pushing the fetus' arm that had suddenly jolted out of the womb back into the womb in order to finish ...
