TO UNDERSTAND HEARING LOSS, IT HELPS TO UNDERSTAND HOW WE HEAR.
WATCH THE VIDEO BELOW FOR A QUICK INTRODUCTION.
Common Causes of Hearing Loss
Damage to the inner ear
Aging and prolonged exposure to loud noise may cause wear and tear on the hairs or nerve cells in the cochlea that send sound signals to the brain. When these hairs or nerve cells are damaged or missing, electrical signals aren’t transmitted as efficiently, and hearing loss occurs. Higher pitched tones may become muffled to you. It may become difficult for you to pick out words against background noise. Heredity may make you more prone to these changes. This type of hearing loss is known as sensorineural hearing loss, which is permanent.
A gradual buildup of earwax
Earwax can block the ear canal and prevent the conduction of sound waves. Earwax blockage can be a cause of hearing loss among people of all ages. This can cause a conductive hearing loss, which usually can be treated with earwax removal.
Ear infection and abnormal bone growths or tumors
In the outer or middle ear, any of these can cause hearing loss.
Ruptured eardrum (tympanic membrane perforation)
Loud blasts of noise, sudden changes in pressure, poking your eardrum with an object and/or infection can cause your eardrum to rupture and affect your hearing.
