White noise does not induce fetal sleep.
White noise has been shown to induce sleep in newborns. We sought to examine whether this type of sound will also induce a quiet state in the fetus. Twenty-two fetuses at 36-41 weeks of gestation were exposed to white noise during an active state. The sound was delivered for 5 min at an intensity of 100 dB. No significant change in fetal activity was noted following the sound.
