Heredity seems to be the most common of the causes of hearing loss in children. Hearing loss doesn’t seem to be passed down from one generation to the next. Most children born deaf have parents who are hearing.
When a child is born deaf, that doesn’t necessarily mean the deafness was hereditary. Complications during pregnancy is also one of the causes of hearing loss. In the 1960s, many babies were born deaf because their mothers caught rubella, the German measles, while they were pregnant.
Causes of hearing loss in adults as well as children can also be attributed to specific illnesses including meningitis, prolonged high fever, head injury, and using certain medications.
One half of the adults who have lost their hearing lost it because of continual exposure to loud noise (including loud music) or aging. About 30% of people over the age of 65 experience some hearing loss.
Earwax buildup in your ear canal, fluid buildup in your middle ear, foreign objects in your ear canal, an ear infection, and many more symptoms cause the more common type of hearing loss. Read my Conductive Hearing Loss article to find a more extensive list of causes as well as treatments for this type of hearing loss.
Some causes for the incurable type of hearing loss are: chicken pox, the flu, concussions, and tumors. Read my Sensorineural Hearing Loss article to find a more extensive list of causes as well as treatments for this type of hearing loss.
If you do not want to lose your hearing, I would suggest being protective of your ears, your head, and your health. When you get older, don’t be surprised when you can’t hear much any more. That’s just a way of life. To lessen the amount of hearing you may lose when you age, stay away from loud music. Don’t stand next to the speakers at a concert. And don’t go around hitting your head on things.
If you do want to lose your hearing, I would suggest doing the opposite of everything I just said. Have fun.
