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!
Hearing in the womb. The ear begins to develop during the third week and at twenty weeks a baby's ear resembles an adult's in shape and size. Four weeks later the hearing is fully developed, and a baby can hear voices, music and other sounds outside the womb. The sounds in the womb are muffled, but the melody and rhythm of music are not much altered. A baby's brain registers rhythmic patterns, and changes in beat and melody are picked up.
