Acoustic stimulation in prenatal period is the issue that interest growing group of people. In this paper the ratio of maternal internal sounds (noise) and attenuated sounds from external environment (signal) is considered. There is indicated that only narrow range of frequencies is not drowned by internal sounds. The problem of a distance of sound source was also considered. It was noticed that the application of sound source on maternal abdomen does not increase the sound level in the uterus.
