HEARING LOSS
You may have hearing loss, and not even be aware of it. People of all ages experience gradual hearing loss, often due to the natural aging process or long exposure to loud noise. Other causes of hearing loss include viruses or bacteria, heart conditions or stroke, head injuries, tumors, and certain medications. Treatment for hearing loss will depend on your diagnosis.
How does the hearing sense work?
Hearing is a complex and intricate process. The ear is made up of three sections: the outer ear, the middle ear, and the inner ear. These parts work together so you can hear and process sounds. The outer ear, or pinna (the part you can see), picks up sound waves and directs them into the outer ear canal.
These sound waves travel down the ear canal and hit the eardrum, which causes the eardrum to vibrate. When the eardrum vibrates, it moves three tiny bones in your middle ear. The middle ear is a small air-filled space between the eardrum and the inner ear. These bones form a chain and are called the hammer (or malleus), anvil (or incus), and stirrup (or stapes). The movement of these bones transmits and amplifies the sound waves toward the inner ear.
The third bone in the chain, the stapes, interfaces with fluid which fills the hearing portion of the inner ear -- the cochlea. The cochlea is lined with cells that have thousands of tiny hairs on their surfaces. As the fluid wave travels through the cochlea, it causes the tiny hairs to move. The hairs change the mechanical wave into nerve signals. The nerve signals are then transmitted to your brain, which interprets the sound.
Test your hearing
To get an idea of how well you hear, answer the following questions and then calculate your score. To calculate your score, give yourself 3 points for every “Almost always” answer, 2 points for every “Half the time” answer, 1 point for every “Occasionally” answer, and 0 for every “Never.” Please note: If hearing loss runs in your family, add an additional 3 points to your overall score.
The American Academy of Otolaryngology—Head and Neck Surgery recommends the following:
0-5 points—Your hearing is fine. No action is required.
6-9 points—Suggest you see an ear, nose, and throat (ENT) specialist.
10+ points—Strongly recommend you see an ear, nose, and throat (ENT) specialist.
