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!
Newborns respond to language sounds from any language, not just their own. However, by the age of one year, a baby's response to phonemes becomes more selective. They stop responding to phonemes that are absent from their own linguistic environment. (Kuhl, Williams, Lacerda, Stevens and Lindblom, 1992). Babies who are born deaf do not show phoneme sensitivity, but they show all the other stages of language development when they learn to use sign language. This shows that language development is built in to humans, and it also shows that language does not depend on speaking or hearing words.
