A hearing loss can happen when any part of the ear is not working in the usual way. This includes the outer ear, middle ear, inner ear, hearing (acoustic) nerve, and auditory system. Hearing screening can tell if a child might have hearing loss. Hearing screening is easy and is not painful. In fact, babies are often asleep while being screened. It takes a very short time usually only a few minutes. A genetic cause: About 1 out of 2 cases of hearing loss in babies is due to genetic causes. Some babies with a genetic cause for their hearing loss might have family members who also have a hearing loss. About 1 out of 3 babies with genetic hearing loss have a ?syndrome.? This means they have other conditions in addition to the hearing loss, such as Down syndrome or Usher syndrome.
