The Importance of Early Sound Exposure in the Womb

MIT shares how the auditory system is shaped in the womb.

In the new study, the researchers showed that exposing a computational model of the human auditory system to a full range of frequencies from the beginning led to worse generalization performance on tasks that require absorbing information over longer periods of time — for example, identifying emotions from a voice clip. From the applied perspective, the findings suggest that babies born prematurely may benefit from being exposed to lower-frequency sounds rather than the full spectrum of frequencies that they now hear in neonatal intensive care units, the researchers say.
