There are thousands of different causes of sensorineural hearing loss. Carlson: We call it sensorineural hearing loss. Nerve-related hearing loss is usually permanent.ĭr. Matthew Carlson says temporary hearing loss can happen when your ears are plugged with wax or fluid behind the ear drum, for example. Matthew Carlson, M.D.: There's a lot of different types of hearing loss. Vivien Williams: Hearing loss is very common. Loud blasts of noise, sudden changes in pressure, poking your eardrum with an object and infection can cause your eardrum to rupture and affect your hearing. Ruptured eardrum (tympanic membrane perforation).In the outer or middle ear, any of these can cause hearing loss. Ear infection and abnormal bone growths or tumors.Earwax removal can help restore your hearing. Earwax can block the ear canal and prevent conduction of sound waves. It may become difficult for you to pick out words against background noise. Higher pitched tones may become muffled to you. When these hairs or nerve cells are damaged or missing, electrical signals aren't transmitted as efficiently, and hearing loss occurs. Aging and 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. How hearing loss can occurĭamage to the inner ear. Your brain turns these signals into sound. There, the vibrations pass through fluid in a snail-shaped structure in the inner ear (cochlea).Īttached to nerve cells in the cochlea are thousands of tiny hairs that help translate sound vibrations into electrical signals that are transmitted to your brain. The eardrum and three small bones of the middle ear amplify the vibrations as they travel to the inner ear. Sound waves pass through the outer ear and cause vibrations at the eardrum. Your ear consists of three major areas: outer ear, middle ear and inner ear. The cochlea, a snail-shaped structure, is part of your inner ear. The middle ear is separated from your external ear by the eardrum and connected to the back of your nose and throat by a narrow passageway called the eustachian tube. The middle ear includes three small bones - the hammer (malleus), anvil (incus) and stirrup (stapes).
