A baby's hearing starts developing around 20 weeks after conception and by 23 weeks they are able to hear the sound of their motherâs heartbeat. Eventually as they grow they are able to hear sounds from the outside world and can create an attachment to their parentâs by the sound of their voices. Newborn babies are believed to be able to distinguish the voices of their parents because their hearing develops around 20 weeks after conception.
