Hearing is one of our most important senses. It helps us to communicate, to be warned about danger and to be aware of the world around us.
Nearly 1 out of every 4 Canadian adults report some level of hearing loss or hearing disability. The prevalence of hearing loss rises with age. About 65 percent of people over the age of 70 have hearing problems.
People over the age of 60 should schedule routine hearing tests every 2 years. If hearing loss is detected, hearing tests should be conducted once a year.
What are the signs that you may have hearing loss?
You may have hearing loss if you:
- Find that speech is muffled or unclear
- Ask people to repeat themselves or speak louder
- Have difficulty understanding or following conversations
- Must concentrate to understand what people say
- Have ringing, hissing or clicking noises in your ear
What are the different types of hearing loss?
There are 2 types of hearing loss: conductive hearing loss and sensorineural hearing loss. A person can have hearing loss that is part conductive and part sensorineural.
Conductive hearing loss
Conductive hearing loss is caused by a problem in the outer or middle part of the ear. This may be due to a wax blockage, punctured eardrum or an ear infection. Certain types of conductive hearing loss can be temporary and often can be medically or surgically treated. Those that cannot be treated medically or surgically may be recommended to wear a hearing aid.
Sensorineural hearing loss
Sensorineural hearing loss is caused by a problem with the inner part of the ear or hearing nerve. This type of hearing loss tends to be progressive and permanent. Aging is the number one cause of sensorineural hearing loss. It can also be caused by very loud noise, disease, injury or certain medication. It can also be congenital.
Congenital hearing loss refers to hearing loss that was present when you were born due to genetics or other factors or conditions. It can be hereditary (genetic) or it can be the result of other factors or conditions. This hearing loss can be either conductive, sensorineural or both.
Sudden sensorineural hearing loss
This type of hearing loss is commonly known as sudden deafness. It is most often an unexplained, rapid loss of hearing in one or both ears. The most common causes are viral or bacterial infections, medications that harm the sensory cells in the inner ear, or autoimmune diseases. This type of hearing loss is most commonly treated with corticosteroids.
This type of hearing loss should be considered a medical emergency. Anyone who experiences these symptoms should visit a health care provider immediately.
