Can exposure to loud noises damage an unborn baby's hearing?

Dr. Michael Roizen, MD
Internal Medicine
The way babies' hearing works (and ours, too) is that sound waves stimulate little hairs attached to nerve cells in the cochlea, a tiny shell-shaped structure in the inner part of the ear, which send impulses to the brain. Any damage to those hairs - from loud noises, for example - can affect the functioning of the inner ear. That's why you should protect yourself and your baby, especially if you work in a factory, on the subway, or on the Tarmac.
