Advanced age is the most common cause of hearing loss. One out of three people age 65-74 has some level of hearing loss. After age 75, that goes up to one out of every two people.

However, it's also important to remember that critical or sensitive periods can also affect children in other ways than just neglect or deprivation. For example, there is a critical or sensitive period for language acquisition that occurs during infancy. Children begin learning how to understand and create language from the time they're born. They will absorb and copy the language they hear all around them during that critical or sensitive period early in life. However, for many different reasons, children, and adults, may leave their original home and move to a new country or region where people speak a different language.
