A: Your baby's ears begin to grow when you're about eight weeks pregnant and are completely formed by about 24 weeks. But your baby can start hearing her first sounds -- like your heartbeat or blood whooshing through the umbilical cord -- around 18 weeks, when the bones of the inner ear and the nerve endings from the brain are developed enough. She may even be startled by loud noises!
At 16 weeks the unborn baby is particularly receptive to its motherâs voice. This is because the vibrations that travel through her body to the womb are stronger than noises coming from outside the womb. At 20 â 24 weeks, the unborn baby can recognise the deeper tones of its father's voice. Around 24 weeks. Babies develop preferences for music while in the womb. Fridman (2000)[ 3 ] found that the babiesâ heart rates increased and that they moved around in rhythm to the music.
